 17 | Toolchains Maven Plugin
 18 | =========================
 19 | 
 20 | Extend maven-toolchains-plugin to add JDK auto download and toolchains.xml management.
 21 | 
 22 | # Features
 23 | 
 24 | * JDK auto download by Foojay API support, and install directory is `~/.m2/jdks`
 25 | * Add new toolchain into toolchains.xml dynamically
 26 | * SDKMAN integration: add JDK to toolchains.xml from [SDKMAN](https://sdkman.io/) if SDKMAN detected
 27 | * JBang integration: add/auto-install JDK to toolchains.xml from [JBang](https://www.jbang.dev/) if jbang detected
 28 | 
 29 | # Requirements
 30 | 
 31 | * Maven 3.5+
 32 | * JDK 1.7+
 33 | 
 34 | # How to use?
 35 | 
 36 | Add following plugin configuration to your pom.xml:
 37 | 
 38 | ```xml
 39 | 
 40 | <build>

 73 | # GraalVM support
 74 | 
 75 | * vendor should be `graalvm_ce17` or `graalvm_ce11`
 76 | * version is GraalVM version(not Java version), such as `22.3` or `22.3.0`
 77 | * GraalVM native-image component will be installed automatically

103 | # How to get a list of all supported distributions and JDK versions?
104 | 
105 | Please visit https://api.foojay.io/disco/v3.0/distributions to get all information.
106 | 
107 | * jdk vendor is the value of `api_parameter`
108 | * jdk version value could be any value in `versions` array
109 | 
110 | Or you can use [Maven toolchains CLI](https://github.com/linux-china/maven-toolchains-cli) to get all supported JDKs information.

119 | 
120 | # Different JDK for main/test code
121 | 
122 | Maven has support for using different source and target java versions for your project's main code and tests.
123 | You can add `testJdk` toolchain in `toolchains-maven-plugin` to specify the JDK for test code as 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

 61 | 
 62 |       "Contributor" shall mean Licensor and any individual or Legal Entity

 67 |       this License, each Contributor hereby grants to You a perpetual,

 69 |       copyright license to reproduce, prepare Derivative Works of,

 72 | 
 73 |    3. Grant of Patent License. Subject to the terms and conditions of

 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
