我正在用Kotlin构建一个Gradle插件，该插件可以根据Android构建工具进行编译，因此我可以使用Android Transform API，还可以在运行时从Android插件获取Android构建配置。到目前为止，我对此配置没有任何问题：
apply plugin: 'java-gradle-plugin'
apply plugin: 'kotlin'
apply plugin: 'maven'
repositories {
google()
jcenter()
}
dependencies {
implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
implementation 'commons-io:commons-io:2.6'
implementation 'org.ow2.asm:asm:7.0'
compileOnly gradleApi()
compileOnly('com.android.tools.build:gradle:3.2.1') {
exclude group: 'org.jetbrains.kotlin'
}
}
compileKotlin {
kotlinOptions {
jvmTarget = "1.8"
}
}
compileTestKotlin {
kotlinOptions {
jvmTarget = "1.8"
}
}
请注意，我必须从Android构建工具库中排除Kotlin传递依赖项，否则可能会收到Kotlin版本警告。这很好。
但是，当我将Android构建工具升级到3.3.0 时，在Gradle构建过程中会收到以下警告：
w：类路径中的某些JAR文件具有Kotlin Runtime库 捆绑在一起。这可能导致难以调试的问题，如果 有一个不同版本的Kotlin Runtime库 类路径。考虑从类路径中删除这些库
w：/path/to/.gradle/caches/modules-2/files-2.1/com.android.tools.build/builder/3.3.0/de1cc306a8a198f59d56cb9a909d9a4f516116e7/builder-3.3.0.jar： 库中捆绑了Kotlin运行时
该警告在实践中似乎没有带来任何问题（一切仍然可以构建并运行），但是显然我不喜欢在那里发出警告，而且我也不知道是什么原因引起的。当我查看依赖关系树时，我什至没有看到任何不是来自我自己的声明的捆绑的Kotlin库：
compileClasspath - Compile classpath for compilation 'main' (target (jvm)).

有什么方法可以清除此警告，还是我在这里查看错误？
Gradle版本为5.1.1。
答案 0 :(得分：0)
我跟踪了道格在评论中链接的问题跟踪器，发现如果有人想知道，此问题已在 Android Studio 3.3 和 Android Studio 3.4 中得到解决。 / p>
