我的pom文件列表

...但是在mvn clean install上，我得到了
[INFO] -------------------------------------------------------------
[ERROR] COMPILATION ERROR :
[INFO] -------------------------------------------------------------
[ERROR] Failure executing javac, but could not parse the error:
javac: invalid target release: 1.7
Usage: javac <options> <source files>/usr/bin/java -version是(此处为which java points )
java version "1.7.0_10"
Java(TM) SE Runtime Environment (build 1.7.0_10-b18)
Java HotSpot(TM) 64-Bit Server VM (build 23.6-b04, mixed mode)javac还指向正确的Java版本
/usr/bin/javac -> /Library/Java/JavaVirtualMachines/jdk1.7.0_10.jdk/Contents/Home/bin/javac在这台机器上，我使用的是zsh (echo $0返回-zsh)
在我的.zshrc中，我定义了：
33 # HOME
34 JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_10.jdk/Contents/Home
35 SCALA_HOME=/Library/Scala/current
36 FORGE_HOME=~/tools/forge/
37
38 # PATH
39 PATH="/Library/Frameworks/Python.framework/Versions/3.2/bin:${PATH}"
40 PATH=${PATH}:${JAVA_HOME}/bin
41 PATH=${PATH}:/bin/
42 PATH=${PATH}:/sbin/
43 PATH=${PATH}:/usr/bin/
44 PATH=${PATH}:/usr/sbin/
45 PATH=${PATH}:/opt/local/bin/
46 PATH=${PATH}:/opt/local/sbin/
47 PATH=${PATH}:/usr/local/git/bin
48 PATH=${PATH}:/usr/local/git/sbin
49 PATH=${PATH}:/Applications/Xcode.app/Contents/Developer/usr/bin
50 PATH=${PATH}:${SCALA_HOME}/bin
51 PATH=${PATH}:${FORGE_HOME}/bin
52
53 export PATH当我运行mvn clean install --debug时，我发现实际上我使用的是Java6
1 Apache Maven 3.0.3 (r1075438; 2011-02-28 11:31:09-0600)
2 Maven home: /usr/share/maven
3 Java version: 1.6.0_35, vendor: Apple Inc.
4 Java home: /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home它可以在哪里定义？我有源(D)我的.zshrc多次。

检查maven安装中的mvn脚本，看看它是如何构建命令的。也许您或其他人在其中硬编码了一个JAVA_HOME，但却忘记了它。

我也有同样的问题，为了解决这个问题，我关注了这篇博客文章：http://www.mkyong.com/java/how-to-set-java_home-environment-variable-on-mac-os-x/
$ vim .bash_profile
export JAVA_HOME=$(/usr/libexec/java_home)
$ source .bash_profile
$ echo $JAVA_HOME
/Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home@mkyong的特殊tks

请查看您的pom.xml以获取以下标签
<properties>
<maven.compiler.source>1.7</maven.compiler.source>
<maven.compiler.target>1.7</maven.compiler.target>
</properties>它应该指向所需的jdk版本
