Gradle，shadowJar:在任务内部使用重定位 [英] Gradle, shadowJar: use relocate inside task

问题描述

我有以下任务:

task myJar(type: Jar) {
    archiveName = 'myJar.jar'
    includeEmptyDirs = false
    destinationDir = rootProject.libsDir
    dependsOn compileJava

    manifest.attributes('Class-Path': '../lib/commons-lang-2.5.jar')

    into '/', {
        from compileJava.destinationDir
        include 'com/myCompany/project/util/order/**',
                'com/myCompany/project/event/**',
    }
}

，我想将所有类从com/myCompany/project/event/**移至com/myCompany/relocated/project/event/**(以便某些使用我的jar并具有com.myCompany.project的应用定义的.event包将避免任何可能的冲突)

and I would like to relocate all classes from com/myCompany/project/event/** to com/myCompany/relocated/project/event/** (so that some apps using my jar and having com.myCompany.project.event package defined will avoid any possible conflicts)

我发现可以使用影子插件完成此操作，并且尝试添加

I discovered that it can be done using shadow plugin and I tried to add

relocate 'com.myCompany.project.event.', 'com.myCompany.relocated.project.event.'

在此任务下，但似乎不起作用. 有人知道我应该在哪里添加这一行吗?

under this task but it doesn't seem to work. Does anybody know where I should add this line?

推荐答案

您可以通过在build.gradle中添加以下插件来实现此目的

You can achieve this by adding below plugin to your build.gradle

apply plugin: 'com.github.johnrengelman.shadow'

添加此插件后，将以下代码添加到您的build.gradle文件中

After adding this plugin add below code to your build.gradle file

shadowJar {
    relocate 'com.myCompany.project.event', 'com.myCompany.relocated.project.event'
}

添加此代码后，为确保ShadowJar任务在构建之前运行，请在末尾添加此行

After adding this, to ensure your ShadowJar task runs before build, add this line at the end

assemble.dependsOn shadowJar

这将确保在gradle构建期间在组装/构建任务之前触发阴影jar任务.

This will ensure that shadow jar task is triggered before assemble/build task during gradle build.

在完成Gradle构建时，您应该看到所有软件包及其对应的依赖项已从"com.myCompany.project.event"重新定位为"com.myCompany.relocated.project.event".

On doing the Gradle build, you should see all your packages and their corresponding dependencies relocated from 'com.myCompany.project.event' to 'com.myCompany.relocated.project.event'.
