偶尔出现OutOfMemoryError：从Gradle运行Arquillian测试时的Java堆空间

在Mac OS X（Mavericks）上从Gradle运行Arquillian测试时，我经常（但并非总是）遇到以下错误（但遗憾的是，只有当我设置了Gradle

--debug

标志时）。然后，构建将挂起：

我在arquillian.xml文件中使用了javaVmArguments设置，以增加内存。考虑到它偶尔可以使用1024m内存，我尝试了2048m和4096m，但都没有用

<configuration>
   <property name="jbossHome">target/platform-dist/jboss-as-7.1.3.Final</property>
   <property name="serverConfig">standalone-test.xml</property>
   <property name="javaVmArguments">-Xmx2048m -XX:MaxPermSize=256m -Xdebug -Xrunjdwp:server=y,transport=dt_socket,address=8987,suspend=n -Darquillian.testing=true</property>
</configuration>

还有其他人碰到过这个吗？有没有其他地方可以添加内存

谢谢。

如果这是使用

测试任务执行的，您需要设置
测试#maxHeapSize
。异常似乎表明是服务器内存不足，而不是梯度。事实上是这样吗？是的，就是这样。来自@PeterNiederwieser的答案完全正确。
echo $GRADLE_OPTS 
-Xms1024m -Xmx2048m -XX:MaxPermSize=512m
