提问by Mahmoud Saleh
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:
大家好，我已经安装了 maven 2，当我在应用程序根目录中使用 mvn clean 或 mvn install 时它工作正常，但是当尝试在 bash 脚本中使用 maven install 时，我得到了上述异常：
this is my script:
这是我的脚本：
#!/bin/sh
#dirname='/home/myuser/workspace/myapp'
DIRECTORY=$(cd `dirname $ cd $M2_HOME
` && pwd)
cd $DIRECTORY
mvn install -s resources/settings.xml
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 ?
它在 maven 3 上工作正常，但是在我安装了 maven 2 并对其进行了配置后，它停止工作并给了我上述异常，我不知道是什么问题，因为常规构建，mvn install 工作，但是从构建脚本不起作用，有什么想法吗？
