升级到Android插件3.0后，Gradle构建失败

Question

我升级到Android Studio 3.0。构建在我的OS X dev机器上（在IDE和命令行中）都能正常工作，但在我们的Linux构建器（命令行）上失败。

我们的项目有一个app模块，它依赖于common（Java）模块和lib（C ++）模块。 lib模块使用CMake构建，并使用SWIG为C ++代码生成Java API。

在构建器上，:app:javaPreCompileRelease任务在:lib:generateJsonModelRelease之前执行，它启动CMake构建。这导致app模块中的编译错误，因为尚未在lib CMake构建中生成Java类。

有没有办法强制执行此依赖项？我不确定为什么平台/版本之间的行为不同。

...编译应该在CMake构建中生成的缺少Java类的错误

Answer 1

虽然我没有找到让构建正常运行的方法，但我能够分两步运行它：

./gradlew lib:assembleRelease
./gradlew assembleRelease
