gradle-gae-plugin 无法运行 gaeRun

Question

我正在努力证明 gradle 和 gradle-gae-plugin 可以在我们开发 GAE java 后端时为我们完成这项工作。

我取得了一些成功，但随后请了两周的假期，这当然应该受到惩罚......

现在我什至无法启动应用程序。所有依赖项似乎都正确，项目编译正常。

听起来您必须告诉 Java 编译器（我假设您的代码是用 Java 编写的）来设置注释处理。根据我在错误消息中看到的内容，我会尝试以下操作：

禁用注释处理

compileJava.options.compilerArgs = ['-proc:none']

启用注释处理

compileJava.options.compilerArgs = ['-implicit']
