Maven Eclipse插件增加内存？

Question

我已经阅读了其他几个问题和答案，其中没有一个似乎对我有帮助。我正在尝试构建一个mgwt项目，这个项目会有很多排列组合，因此内存设置必须非常高。

我使用maven4eclipse插件来构建以包装为目标，我的运行配置的JRE选项卡上，我设置了以下

vm args:-Xms1024m -Xmx2048m -XX:MaxPermSize=1024m -XX:ReservedCodeCacheSize=64m 

当尝试运行失败，并与该回来错误：

[ERROR] Failed to execute goal org.codehaus.mojo:gwt-maven-plugin:2.3.0-1:compile (default) on project: Command [[ 
[ERROR] **C:\Program Files\Java\jdk1.7.0_17\jre\bin\java -Xmx512m** -classpath "..others stuff" -logLevel INFO -style OBF -war "Branch(mobile)\Project\target\Mobile-webcontent" -localWorkers 8 
[ERROR] ]] failed with status 1 
[ERROR] -> [Help 1] 

这给我看我设置的参数没有被使用，我是否把它设置在错误的地方？

样品POM文件。

gwt-maven-plugin分叉了一个JVM，并且不会继承用于运行Maven的JVM的设置。

如果您需要分叉JVM特定的JVM设置，你可以在你的POM，或-Dgwt.extraJvmArgs="-Xms1g -Xmx2g"在命令行中使用的gwt-maven-plugin的<configuration>的<extraJvmArgs>设置。

见与配置对于大多数GWT编译器选项，包括JVM选项设置为GWT编译http://www.mojohaus.org/gwt-maven-plugin/compile-mojo.html#extraJvmArgs
