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

Question

我有一个Android项目设置与robolectric测试,现在总共约2084个单元测试.但是我一直在考虑添加更多测试的问题java.lang.OutOfMemoryError: PermGen space.

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   

随着strack追踪,我得到以下

* Exception is:

在我的根目录和我的模块目录中的`gradle.properties中,我尝试了以下内容并且没有任何效果.我仍然遇到了内存不足的问题.

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

我尝试过Android Studio Gradle问题的选项:OutOfMemoryError:PermGen空间仍然没有运气.我也一直在看sonarRunner java.lang.OutOfMemoryError:PermGen空间.

希望能得到一些帮助.谢谢

Answer 1

尝试超过512米的数字: org.gradle.jvmargs=-Xmx2048m -XX:MaxPermSize=1024m -Xms512m

正如@Eugen Martynov所提到的如果你使用robolectric gradle插件,你可以将它们指定为DSL 配置

Answer 2

我收集到的信息。

阿卜杜拉（Abdellah）对这个问题给出了一些见解，这与创建的类总数有关。“您已检查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。链接https://github.com/robolectric/robolectric-gradle-plugin#configuration-using-dsl

我的代码的主要问题是，在 PermGen 空间有限的情况下，我在 Mockito 中创建了很多 Spy 对象，这似乎占用了大部分空间。
