IntelliJ Idea 14中的Maven 3.3.1配置错误 [英] Maven 3.3.1 Config Error in IntelliJ Idea 14

问题描述

我从 http://maven.apache.org/download.cgi 获得了maven .tar文件，并且将它安装到路径/ usr / local /。我在新窗口中运行mvn -version命令，输出正确。下面是我的主目录中的.bash_profile：

I got the maven .tar file from http://maven.apache.org/download.cgi, and installed it to the path /usr/local/. I run the mvn -version command in the new window, the output is correct. Below is my .bash_profile in my home directory:

JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk7/Contents/Home  
CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar  
PATH=$JAVA_HOME/bin:$PATH:  
export JAVA_HOME  
export CLASSPATH  
export PATH  
M2_HOME=/usr/local/maven  
M2=$M2_HOME/bin  
PATH=$M2:$PATH  
export M2_HOME    
export M2  
export PATH

且mvn -version低于：

and the mvn -version is below :

BianFranks-MacBook-Pro:~ Frank$ mvn -version  
Apache Maven 3.3.1 (cab6659f9874fa96462afef40fcf6bc033d58c1c; 2015-03-    14T04:10:27+08:00)

但是在Intellij IDEA 14中通过Maven清理模块时提示：

But the tips occurred when cleaning the module via Maven in Intellij IDEA 14:

/Library/Java/JavaVirtualMachines/jdk7/Contents/Home/bin/java -Dmaven.home=/usr/local/maven -Dclassworlds.conf=/usr/local/maven/bin/m2.conf -Didea.launcher.port=7532 "-Didea.launcher.bin.path=/Applications/IntelliJ IDEA 14.app/Contents/bin" -Dfile.encoding=UTF-8 -classpath "/usr/local/maven/boot/plexus-classworlds-2.5.2.jar:/Applications/IntelliJ IDEA 14.app/Contents/lib/idea_rt.jar" com.intellij.rt.execution.application.AppMain org.codehaus.classworlds.Launcher -Didea.version=14.0.2 clean  
-Dmaven.multiModuleProjectDirectory system propery is not set. Check   $M2_HOME environment variable and mvn script match.   
Process finished with exit code 1

系统属性未设置，但我不知道知道如何设置...

the system property is not set, but I don't know how to set it...

推荐答案

打开IntelliJ设置对话框。

Open up the IntelliJ settings dialog.

在Maven中 - > Runner选项设置以下VM选项：
-Dmaven.multiModuleProjectDirectory = project root

In Maven-->Runner options set a following VM option: -Dmaven.multiModuleProjectDirectory=project root
