升级到 Android 插件 3.0 后 Gradle 构建失败

Question

我升级到了 Android Studio 3.0。该构建在我的 OS X 开发机器上运行良好（在 IDE 和命令行中），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，它依赖于一个 common (Java) 模块和一个 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 任务在启动 CMake 构建的 :lib:generateJsonModelRelease 之前执行。这会导致app 模块中的编译错误，因为在lib CMake 构建中尚未生成Java 类。

有没有办法强制执行这种依赖关系？我不确定为什么平台/版本之间的行为不同。

...编译有关缺少应在 CMake 构建中生成的 Java 类的错误

Answer 1

虽然我没有找到让构建正常运行的方法，但我可以分两步运行它：

./gradlew lib:assembleRelease
./gradlew assembleRelease
