hi guys i have maven 2 installed, when i use mvn clean or mvn install in the app root it works fine but when trying to use maven install inside a bash script i got the above exception:
嗨伙计们我安装了maven 2，当我在app root中使用mvn clean或mvn install时它工作正常但是当尝试在bash脚本中使用maven安装时我得到了以上异常：
this is my script:
这是我的脚本：
#!/bin/sh
#dirname='/home/myuser/workspace/myapp'
DIRECTORY=$(cd `dirname $0` && pwd)
cd $DIRECTORY
mvn install -s resources/settings.xml $1
it was working fine with maven 3, but after i installed maven 2 and configured it, it stopped working and gave me above exception, i don't know what is the problem, since the regular build, mvn install works, but building from the script doesn't work, any ideas ?
它与maven 3工作正常，但在我安装maven 2并配置它之后，它停止工作并给了我以上异常，我不知道是什么问题，因为常规构建，mvn安装工作，但建立从脚本不起作用，有什么想法吗？

Couple of possibilities...
几种可能性......
- One, as posted here, you have both M2_REPO and M3_REPO variables defined.
- 一，如此处所述，您同时定义了M2_REPO和M3_REPO变量。
- Or you are facing this issue related to maven3 and M2_HOME
- 或者您正面临与maven3和M2_HOME相关的此问题
- The other is that somehow the JRE is getting used instead of JDK when run from the batch file!
- 另一个是从批处理文件运行时，不知何故JRE被用来代替JDK！
