Google应用引擎的gradle单元测试在哪里需要persistence.xml？

I have created a Google app engine project using an maven archetype project with the Datanucleus JPA provider, essentially following the Google app engine documentation.

我使用与Datanucleus JPA提供商的maven原型项目创建了一个Google应用引擎项目，主要遵循Google应用引擎文档。

Everything works fine when running the maven goal "test".

当运行maven目标“test”时，一切正常。

Now I had to integrate the project into Android studio and wanted to migrate the build script to gradle. I copied all dependencies from the pom.xml to the build.gradle and the project builds fine. However, all tests that access the Google datastore fail.

现在我必须将项目集成到Android studio中，并希望将构建脚本迁移到gradle。我将所有依赖项从pom.xml复制到build.gradle，项目构建正常。但是，访问Google数据存储区的所有测试都会失败。

During test output I get the following message:

在测试输出期间，我收到以下消息：

Warning:No META-INF/persistence.xml files were found in the CLASSPATH of the current thread!

警告：在当前线程的CLASSPATH中找不到META-INF / persistence.xml文件！

I checked the build folder which is created during the build and no folder contains the persistence.xml from src/main/webapp/WEB-INF/classes/META-INF

我检查了构建期间创建的构建文件夹，没有文件夹包含src / main / webapp / WEB-INF / classes / META-INF中的persistence.xml

Using maven, however, it is correctly put in the target/myapp-1.0-SNAPSHOT/WEB-INF/classes/META-INF folder.

但是，使用maven，它被正确放入target / myapp-1.0-SNAPSHOT / WEB-INF / classes / META-INF文件夹中。

I have tried copying the persistence.xml using a gradle copy task into various locations, such as build/classes/META-INF build/classes/webapp/WEB-INF/classes/META-INF and so on, but nothing worked.

我已经尝试使用gradle复制任务将persistence.xml复制到各个位置，例如build / classes / META-INF build / classes / webapp / WEB-INF / classes / META-INF等，但没有任何效果。

Just because the file is placed in a directory doesn't automatically mean it's in the CLASSPATH.

仅仅因为文件放在目录中并不会自动意味着它在CLASSPATH中。

Place the META-INF folder containing persistence.xml in /src/main/resources.

将包含persistence.xml的META-INF文件夹放在/ src / main / resources中。
