我正在尝试使用 gradle 运行 Android 构建。只要我不缩小它就可以正常工作。当我启用 minify (minifyEnabled true) 时，构建总是失败，因为“无法为 proguard.gradle.ProGuardTask 生成代理类”。
WARNING [Project: :phone] Support for libraries with same package name is deprecated and will be removed in 1.0
running signingConfigs
running proguard
FAILURE: Build failed with an exception.
* What went wrong:
A problem occurred configuring project ':phone'.
> Could not generate a proxy class for class proguard.gradle.ProGuardTask.
* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
BUILD FAILED
我使用 minify 的 gradle 文件部分：
buildTypes {
release {
println "running proguard"
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-project.txt'
signingConfig signingConfigs.release
}
debug {
debuggable true
}
}
只需要一些帮助知道在哪里看...谢谢。
完整的堆栈跟踪
