Windows下的Maven安装:"JAVA_HOME设置为无效目录"

Question

我是Maven的新手,我已经下载了3.0.5版本.我收到以下错误:

JAVA_HOME is set to an invalid directory. please set the java_home variable in your environment variable to match the location of your java installation

虽然,我在命令提示符下输入javac或回显时看不到任何错误%M2_HOME%.

我有以下路径变量集 -

CLASSPATH - ;C:\Program Files (x86)\Java\jdk1.7.0_40\lib;
JAVA_HOME - C:\Program Files (x86)\Java\jdk1.7.0_40\bin
M2 - %M2_HOME%\bin
M2_HOME - C:\Users\cbil\Documents\Maven\apache-maven-3.0.5-bin\apache-maven-3.0.5
MAVEN_OPTS - -Xms256m -Xmx512m
PATH - C:\Program Files\Java\jdk1.7.0_45\bin;C:\Users\cbil\Documents\Maven\apache-maven-3.0.5-bin\apache-maven-3.0.5\bin;

有人可以帮帮我吗？

Answer 1

• M2_HOME 指向安装maven的目录.
• M2指向maven下的bin目录
• JAVA_HOME 指向系统上安装的JDK目录.

从以下设置再次验证:

JAVA_HOME   - C:\Program Files\Java\jdk1.6.0_23
M2_HOME     - D:\Software\apache-maven-3.0.5
M2          - %M2_HOME%\bin
PATH        - %M2%;%JAVA_HOME%\bin

Answer 2

设置JAVA_HOME

set JAVA_HOME=C:\Program Files (x86)\Java\jdk1.7.0_40

添加mvn到路径

set PATH=%PATH%;C:\Users\cbil\Documents\Maven\apache-maven-3.0.5-bin\apache-maven-3.0.5\bin;
