This is no real semantic versioning because the SHADOW_MAJOR version number correspond to the MAJOR shadow plugin version number. 16 | 17 | 18 | At the time of writing, the latest shadow plugin version was `2.0.2`. Therefore, you should use this library's version starting with `2`. 19 | If you are stuck at version `1.2.4` use the library version starting with `1`. 20 | 21 | ## Latest Version 22 | [![Download](https://api.bintray.com/packages/theboegl/gradle-plugins/shadow-log4j-transformer/images/download.svg) ](https://bintray.com/theboegl/gradle-plugins/shadow-log4j-transformer/_latestVersion)
23 | The latest library version is `2.2.0`. It requires at least __Java 7__. 24 | 25 | You can get version notifications on bintray:
[![Get automatic notifications about new "shadow-log4j-transformer" versions](https://www.bintray.com/docs/images/bintray_badge_color.png)](https://bintray.com/theboegl/gradle-plugins/shadow-log4j-transformer?source=watch) 26 | 27 | ## Adding the transformer implementation to your project 28 | 29 | This implementation must work with the __shadow plugin__ and will use __Log4j 2__. 30 | 31 | You should use this implementation as library. 32 | You may use it as gradle plugin though this is not recommended anymore due to issues (e.g. [#2](https://github.com/TheBoegl/shadow-log4j-transformer/issues/2), [#3](https://github.com/TheBoegl/shadow-log4j-transformer/issues/3) and, [#5](https://github.com/TheBoegl/shadow-log4j-transformer/issues/5)). 33 | 34 | ### Usage as library 35 | 36 | The implementation should be used as library to provide the Log4j 2 transformer. 37 | This is as easy as shown below: 38 | 39 | ```gradle 40 | buildscript { 41 | dependencies { 42 | classpath "com.github.jengelman.gradle.plugins:shadow:2.0.2" 43 | classpath 'de.sebastianboegl.gradle.plugins:shadow-log4j-transformer:2.2.0' 44 | } 45 | } 46 | 47 | apply plugin: 'com.github.johnrengelman.shadow' 48 | 49 | shadowJar { 50 | transform(de.sebastianboegl.gradle.plugins.shadow.transformers.Log4j2PluginsFileTransformer) 51 | } 52 | ``` 53 | 54 | ### Not recommended: Using the `apply` method 55 | The plugin applies the latest version of the shadow plugin or the one in the dependency block, hence, you don't have to apply the shadow plugin. 56 | 57 | ```gradle 58 | buildscript { 59 | repositories { 60 | maven { 61 | url "https://plugins.gradle.org/m2/" 62 | } 63 | } 64 | dependencies { 65 | classpath "com.github.jengelman.gradle.plugins:shadow:2.0.2" 66 | classpath "de.sebastianboegl.gradle.plugins:shadow-log4j-transformer:2.2.0" 67 | } 68 | } 69 | 70 | apply plugin: "de.sebastianboegl.shadow.transformer.log4j" 71 | ``` 72 | 73 | ### Not recommended: Using the Gradle plugin DSL 74 | The order of the plugins doesn't matter: 75 | 76 | ```gradle 77 | plugins { 78 | id "com.github.johnrengelman.shadow" version "2.0.2" 79 | id "de.sebastianboegl.shadow.transformer.log4j" version "2.2.0" 80 | } 81 | ``` 82 | 83 | ## Configuration 84 | There is __no__ configuration needed. 85 | The plugin adds itself as [Transformer](http://imperceptiblethoughts.com/shadow/api/com/github/jengelman/gradle/plugins/shadow/transformers/Transformer.html) (see the shadow plugin documentation [Section Controlling JAR Content Merging](http://imperceptiblethoughts.com/shadow/#controlling_jar_content_merging)). 86 | -------------------------------------------------------------------------------- /build.gradle:
