我如何获得m2eclipse来识别$ M2_OPTS? [英] How do I get m2eclipse to recognize $M2_OPTS?

问题描述

看来m2eclipse无法识别我的$ M2_OPTS变量.

It appears m2eclipse is not recognizing my $M2_OPTS variable.

我可以在eclipse fine之外运行相同的构建(使用增大的heapsize):

I can run the same build outside of eclipse fine (with cranked up heapsize):

[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESSFUL

[INFO] Finished at: Tue Nov 10 00:00:02 EST 2009
[INFO] Final Memory: 72M/187M

但是当我使用m2eclipse运行它时，我总是用光内存:

But when I run this with m2eclipse I always run out of memory:

[INFO] ------------------------------------------------------------------------

有什么想法吗?

解决方案:将mem args添加到Java首选项的Installed JREs标签中.

SOLUTION : Add the mem args to the Installed JREs tab of the Java preferences.

推荐答案

当前存在与此相关的问题，请参见

There is currently an issue about this, see MNGECLIPSE-1182, and a workaround:

...您可以在窗口"/首选项"/"Java"/已安装的JRE"中指定默认的JVM参数.

... you can specify default JVM arguments in Window / Preferences / Java / Installed JREs.

但实际上，此评论使我感到困惑:

But actually, this comment is confusing me:

[似乎当前 m2eclipse插件仍然很荣幸 M2_OPTS环境变量何时 使用外部Maven安装.

[ It appears as though the current m2eclipse plugin still honors the M2_OPTS environment variable when using an external maven installation.

所以我只定义了两个: MAVEN_OPTS用于从中运行mvn 命令提示符和M2_OPTS 从m2eclipse运行Maven.例如.放 M2_OPTS=-Xmx256M -XX:MaxPermSize=128M

So I just defined both of them: MAVEN_OPTS for running mvn from command prompts and M2_OPTS for running maven from m2eclipse. E.g. set M2_OPTS=-Xmx256M -XX:MaxPermSize=128M

我正在使用Maven 2.1.0和Maven 集成Eclipse版本 0.9.9.200907071528和Eclipse Galileo. ]
