-------------------------------------------------------------------------------- 1 | ## 超快编译源文件的Gradle插件，支持Java和Kotlin 2 | 3 |
4 | 5 | ### 博客详情：敬请期待。。。 6 | 7 |
8 | 9 | ### 介绍： 10 | 插件源自WanAndroid每日一问：[极致的编译优化如何实现？](https://wanandroid.com/wenda/show/18453) 11 | 12 | 插件提供了2个Task：*incremental/incrementalCompile*（增量编译源文件）、*incremental/generateIncrementalDex*（增量编译 + 生成增量dex）； 13 | 14 | 每次只会编译有改动的源文件，增量编译过程中不依赖Android Gradle Plugin的任何一个Task（除了需要生成R文件和BuildConfig的时候）； 15 | 16 | 与Android Gradle Plugin的*assemble* Task共享编译记录（它编译过的文件且无改动的话，插件Task不会再编译，插件编译过的文件无改动的话它也不会再次编译）； 17 | 18 | 19 | >需要clone代码进行本地测试的同学，我在`plugin/build.gradle.kts`里面已把详细步骤说明，这里就不赘述了。 20 | 21 |
22 | 23 | ### 大致原理： 24 | 研究了*assembleDebug*的增量编译的大致原理（Java），发现它是通过JavaCompile的`compile`方法来完成对.java文件的编译的，这个方法有个叫`inputChanges`的参数，它描述了哪些文件在上一次编译后有改动，实现增量编译最重要就是这个参数了。 25 | 26 | **那它是怎么知道哪些文件有改动的呢？** 27 | 28 | 是这样的，*assembleDebug*在每次编译完成之后，都会把本次参与编译的源文件的指纹（md5sum）记录在`project/.gradle/gradle-version/executionHistory/executionHistory.bin`文件里 。如果是第一次编译，那就是全部源文件了，后面每次只保存有变更的，因为没变更的不需要参与编译，它的md5也不会变。 29 | 30 | 指纹对比与直接对比修改日期有个优点就是，只要内容不变它的指纹都是不变的，而判断修改日期的话，可能那个文件刚开始有修改过，但在编译之前又撤销了修改，这样它的修改日期依然会变更。 31 | 32 | **插件的做法是：** 33 | 34 | 初始化完成后直接拿到*compileDebugJavaWithJavac*和*compileDebugKotlin*（如果项目支持Kotlin的话）所对应的Compile（负责编译文件的类）； 35 | 36 | 在进行一些基本的配置之后，使用跟*assembleDebug*相同的方式来计算出本次变更的文件，并交给Compile处理； 37 | 38 | Compile编译完成后，把这些参与编译的文件记录到*assembleDebug*这个Task所使用的ExecutionHistoryStore中； 39 | 40 | 如果运行的是*generateIncrementalDex*，还会借助D8工具（D8是SDK 28之后才存在`build-tools`里，这就是为什么要求*compileSdkVersion*不低于28的原因）来把这些类打包到dex里面。 41 | 42 | 43 |
44 | 45 | ### 效果演示： 46 | 随意改动不同module的几个文件： 47 | 48 | ![preview](https://github.com/wuyr/incremental-compiler/raw/main/previews/0.png) 49 | 50 | 通过*generateIncrementalDex*来生成增量dex： 51 | 52 | ![preview](https://github.com/wuyr/incremental-compiler/raw/main/previews/5.png) 53 | 54 | ![preview](https://github.com/wuyr/incremental-compiler/raw/main/previews/1.png) 55 | 56 | Task执行完毕后，在`project/build/outputs/merged_incremental_dex`目录下会生成`classes.dex`： 57 | 58 | ![preview](https://github.com/wuyr/incremental-compiler/raw/main/previews/2.png) 59 | 60 | 直接打开，会发现刚刚2个module中有改动的3个类都在里面了： 61 | 62 | ![preview](https://github.com/wuyr/incremental-compiler/raw/main/previews/3.png) 63 | 64 |
65 | 66 | ### 使用方式： 67 | #### 新版Gradle： 68 | ```groovy 69 | plugins { 70 | ... 71 | id "com.github.wuyr.incrementalcompiler" version "1.0.0" 72 | } 73 | ``` 74 | #### 旧版Gradle： 75 | 在项目下的`build.gradle`（注意不是`module/build.gradle`，是**项目根目录**下的`build.gradle`哦）加上maven地址和classpath，像这样： 76 | ```groovy 77 | buildscript { 78 | ... 79 | repositories { 80 | ... 81 | maven { url "https://plugins.gradle.org/m2/" } 82 | } 83 | 84 | dependencies { 85 | ... 86 | classpath "com.github.wuyr.incrementalcompiler:plugin:1.0.0" 87 | } 88 | } 89 | ``` 90 | 91 | >如果上面的`plugins.gradle.org/m2`访问速度很慢，也可以换成国内的镜像地址，比如阿里云的：
maven { url 'https://maven.aliyun.com/nexus/content/repositories/gradle-plugin' } 92 | 93 | 然后在目标module里加上： 94 | ```groovy 95 | apply plugin: "com.github.wuyr.incrementalcompiler" 96 | ``` 97 | 即可。 98 | 99 |
100 | 101 | #### 应用到所有module： 102 | 如果想为项目中所有module应用的话，可以在项目下的`build.gradle`（注意不是`module/build.gradle`，是**项目根目录**下的`build.gradle`哦）中直接遍历所有module，像这样： 103 | ```groovy 104 | subprojects { 105 | apply plugin: 'com.github.wuyr.incrementalcompiler' 106 | } 107 | ``` 108 | 109 |
110 | 111 | ### 要求： 112 | - *Gradle Version*不低于**6.1.1** 113 | 114 | - *Android Gradle Plugin Version*不低于**3.6.0** 115 | 116 | - *compileSdkVersion*/*buildToolsVersion*不低于**28** 117 | 118 |

  6 | 
  7 |    1. Definitions.
  8 |

 11 | 
 12 |       "Licensor" shall mean the copyright owner or entity authorized by
 13 |       the copyright owner that is granting the License.
 14 | 
 15 |       "Legal Entity" shall mean the union of the acting entity and all
 16 |       other entities that control, are controlled by, or are under common
 17 |       control with that entity. For the purposes of this definition,
 18 |       "control" means (i) the power, direct or indirect, to cause the
 19 |       direction or management of such entity, whether by contract or
 20 |       otherwise, or (ii) ownership of fifty percent (50%) or more of the

 22 | 
 23 |       "You" (or "Your") shall mean an individual or Legal Entity
 24 |       exercising permissions granted by this License.
 25 | 
 26 |       "Source" form shall mean the preferred form for making modifications,

 28 |       source, and configuration files.
 29 | 
 30 |       "Object" form shall mean any form resulting from mechanical
 31 |       transformation or translation of a Source form, including but
 32 |       not limited to compiled object code, generated documentation,
 33 |       and conversions to other media types.
 34 | 
 35 |       "Work" shall mean the work of authorship, whether in Source or
 36 |       Object form, made available under the License, as indicated by a
 37 |       copyright notice that is included in or attached to the work
 38 |       (an example is provided in the Appendix below).
 39 | 
 40 |       "Derivative Works" shall mean any work, whether in Source or Object
 41 |       form, that is based on (or derived from) the Work and for which the
 42 |       editorial revisions, annotations, elaborations, or other modifications
 43 |       represent, as a whole, an original work of authorship. For the purposes
 44 |       of this License, Derivative Works shall not include works that remain
 45 |       separable from, or merely link (or bind by name) to the interfaces of,
 46 |       the Work and Derivative Works thereof.
 47 | 
 48 |       "Contribution" shall mean any work of authorship, including
 49 |       the original version of the Work and any modifications or additions
 50 |       to that Work or Derivative Works thereof, that is intentionally
 51 |       submitted to Licensor for inclusion in the Work by the copyright owner
 52 |       or by an individual or Legal Entity authorized to submit on behalf of
 53 |       the copyright owner. For the purposes of this definition, "submitted"
 54 |       means any form of electronic, verbal, or written communication sent
 55 |       to the Licensor or its representatives, including but not limited to
 56 |       communication on electronic mailing lists, source code control systems,
 57 |       and issue tracking systems that are managed by, or on behalf of, the
 58 |       Licensor for the purpose of discussing and improving the Work, but
 59 |       excluding communication that is conspicuously marked or otherwise
 60 |       designated in writing by the copyright owner as "Not a Contribution."
 61 | 
 62 |       "Contributor" shall mean Licensor and any individual or Legal Entity
 63 |       on behalf of whom a Contribution has been received by Licensor and
 64 |       subsequently incorporated within the Work.
 65 | 
 66 |    2. Grant of Copyright License. Subject to the terms and conditions of
 67 |       this License, each Contributor hereby grants to You a perpetual,
 68 |       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
 69 |       copyright license to reproduce, prepare Derivative Works of,
 70 |       publicly display, publicly perform, sublicense, and distribute the
 71 |       Work and such Derivative Works in Source or Object form.
 72 | 
 73 |    3. Grant of Patent License. Subject to the terms and conditions of
 74 |       this License, each Contributor hereby grants to You a perpetual,
 75 |       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
 76 |       (except as stated in this section) patent license to make, have made,
 77 |       use, offer to sell, sell, import, and otherwise transfer the Work,
 78 |       where such license applies only to those patent claims licensable
 79 |       by such Contributor that are necessarily infringed by their
 80 |       Contribution(s) alone or by combination of their Contribution(s)
 81 |       with the Work to which such Contribution(s) was submitted. If You
 82 |       institute patent litigation against any entity (including a
 83 |       cross-claim or counterclaim in a lawsuit) alleging that the Work
 84 |       or a Contribution incorporated within the Work constitutes direct
 85 |       or contributory patent infringement, then any patent licenses
 86 |       granted to You under this License for that Work shall terminate
 87 |       as of the date such litigation is filed.
 88 | 
 89 |    4. Redistribution. You may reproduce and distribute copies of the
 90 |       Work or Derivative Works thereof in any medium, with or without
 91 |       modifications, and in Source or Object form, provided that You
 92 |       meet the following conditions:
 93 | 
 94 |       (a) You must give any other recipients of the Work or
 95 |           Derivative Works a copy of this License; and
 96 | 
 97 |       (b) You must cause any modified files to carry prominent notices
 98 |           stating that You changed the files; and
 99 | 
100 |       (c) You must retain, in the Source form of any Derivative Works
101 |           that You distribute, all copyright, patent, trademark, and
102 |           attribution notices from the Source form of the Work,
103 |           excluding those notices that do not pertain to any part of
104 |           the Derivative Works; and
105 | 
106 |       (d) If the Work includes a "NOTICE" text file as part of its
107 |           distribution, then any Derivative Works that You distribute must
108 |           include a readable copy of the attribution notices contained
109 |           within such NOTICE file, excluding those notices that do not
110 |           pertain to any part of the Derivative Works, in at least one
111 |           of the following places: within a NOTICE text file distributed
112 |           as part of the Derivative Works; within the Source form or
113 |           documentation, if provided along with the Derivative Works; or,
114 |           within a display generated by the Derivative Works, if and
115 |           wherever such third-party notices normally appear. The contents
116 |           of the NOTICE file are for informational purposes only and
117 |           do not modify the License. You may add Your own attribution
118 |           notices within Derivative Works that You distribute, alongside
119 |           or as an addendum to the NOTICE text from the Work, provided
120 |           that such additional attribution notices cannot be construed
121 |           as modifying the License.
122 | 
123 |       You may add Your own copyright statement to Your modifications and
124 |       may provide additional or different license terms and conditions
125 |       for use, reproduction, or distribution of Your modifications, or
126 |       for any such Derivative Works as a whole, provided Your use,
127 |       reproduction, and distribution of the Work otherwise complies with
128 |       the conditions stated in this License.
129 | 
130 |    5. Submission of Contributions. Unless You explicitly state otherwise,
131 |       any Contribution intentionally submitted for inclusion in the Work
132 |       by You to the Licensor shall be under the terms and conditions of
133 |       this License, without any additional terms or conditions.
134 |       Notwithstanding the above, nothing herein shall supersede or modify
135 |       the terms of any separate license agreement you may have executed
136 |       with Licensor regarding such Contributions.
137 | 
138 |    6. Trademarks. This License does not grant permission to use the trade
139 |       names, trademarks, service marks, or product names of the Licensor,
140 |       except as required for reasonable and customary use in describing the
141 |       origin of the Work and reproducing the content of the NOTICE file.
142 | 
143 |    7. Disclaimer of Warranty. Unless required by applicable law or
144 |       agreed to in writing, Licensor provides the Work (and each
145 |       Contributor provides its Contributions) on an "AS IS" BASIS,
146 |       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
147 |       implied, including, without limitation, any warranties or conditions
148 |       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
149 |       PARTICULAR PURPOSE. You are solely responsible for determining the
150 |       appropriateness of using or redistributing the Work and assume any
151 |       risks associated with Your exercise of permissions under this License.
152 | 
153 |    8. Limitation of Liability. In no event and under no legal theory,
154 |       whether in tort (including negligence), contract, or otherwise,
155 |       unless required by applicable law (such as deliberate and grossly
156 |       negligent acts) or agreed to in writing, shall any Contributor be
157 |       liable to You for damages, including any direct, indirect, special,
158 |       incidental, or consequential damages of any character arising as a
159 |       result of this License or out of the use or inability to use the
160 |       Work (including but not limited to damages for loss of goodwill,
161 |       work stoppage, computer failure or malfunction, or any and all
162 |       other commercial damages or losses), even if such Contributor
163 |       has been advised of the possibility of such damages.
164 | 
165 |    9. Accepting Warranty or Additional Liability. While redistributing
166 |       the Work or Derivative Works thereof, You may choose to offer,
167 |       and charge a fee for, acceptance of support, warranty, indemnity,
168 |       or other liability obligations and/or rights consistent with this
169 |       License. However, in accepting such obligations, You may act only
170 |       on Your own behalf and on Your sole responsibility, not on behalf
171 |       of any other Contributor, and only if You agree to indemnify,
172 |       defend, and hold each Contributor harmless for any liability
173 |       incurred by, or claims asserted against, such Contributor by reason
174 |       of your accepting any such warranty or additional liability.
175 | 
176 |    END OF TERMS AND CONDITIONS
177 | 
178 |    APPENDIX: How to apply the Apache License to your work.
179 | 
180 |       To apply the Apache License to your work, attach the following
181 |       boilerplate notice, with the fields enclosed by brackets "[]"
182 |       replaced with your own identifying information. (Don't include
183 |       the brackets!)  The text should be enclosed in the appropriate
184 |       comment syntax for the file format. We also recommend that a
185 |       file or class name and description of purpose be included on the
186 |       same "printed page" as the copyright notice for easier
187 |       identification within third-party archives.
188 |
