Android Robolectric Gradle - java.lang.OutOfMemoryError: PermGen space

Question

我有一个 android 项目设置和 robolectric 测试，现在总共有大约 2084 个单元测试。但是由于 java.lang.OutOfMemoryError: PermGen space，我在添加更多测试时遇到了问题。

objc[11380]: Class JavaLaunchHelper is implemented in both /Library/Java/JavaVirtualMachines/jdk1.7.0_71.jdk/Contents/Home/bin/java and /Library/Java/JavaVirtualMachines/jdk1.7.0_71.jdk/Contents/Home/jre/lib/libinstrument.dylib. One of the two will be used. Which one is undefined.
java.lang.OutOfMemoryError: PermGen space                        
Exception in thread "Test worker" java.lang.OutOfMemoryError: PermGen space
Exception in thread "Thread-0" java.lang.OutOfMemoryError: PermGen space
:app:testDebug FAILED

通过 strack 跟踪，我得到以下内容

* Exception is:

在我的 `gradle.properties 根目录和我的模块目录中，我尝试放置以下内容但没有任何效果。我仍然遇到内存不足的问题。

org.gradle.jvmargs=-Xmx1024m -XX:MaxPermSize=512m -Xms512m

我已经尝试了 Android Studio Gradle Issue: OutOfMemoryError: PermGen space still no luck. I also have been looking at sonarRunner java.lang.OutOfMemoryError: PermGen space 中的选项。

希望得到一些帮助。谢谢

Answer 1

尝试大于 512m 的数字：org.gradle.jvmargs=-Xmx2048m -XX:MaxPermSize=1024m -Xms512m

如@Eugen Martynov 所述，如果您使用 robolectric gradle 插件，您可以将它们指定为 DSL configuration

Answer 2

我收集到的信息。

Abdellah 对这个问题给出了一些见解，它与创建的类总数有关。 "you have check https://plumbr.eu/outofmemoryerror/permgen-space "

Eugen Martynov 还提到了我可以添加的 robolectric gradle 插件配置中的参数。 Link 在 https://github.com/robolectric/robolectric-gradle-plugin#configuration-using-dsl

我的代码的主要问题是使用有限的 PermGen space，我在 Mockito 中创建了很多 Spy 对象，这似乎占用了大部分 space。
