The target version can be seen according to maven-compiler-plugin the configuration is JDK 1.7;

According to the above information can be seen my JDK version is also 1.7;

So where's the problem?

Finally I really want to, originally Maven refers to the 1.6 version, then how to modify the configuration to 1.7 version?

Originally, Maven read two configuration files, /etc/mavenrc and ~/.mavenrc . Two files default is not, you can choose one to make changes, I choose my user directory ~/.mavenrc , the following code to write.

Java_home= '/usr/libexec/java_home '

If you have more than one version of the JDK installed on your Mac and you don't want to change the default JDK version, you just need to add a version number to the configuration, such as:

Java_home= '/usr/libexec/java_home-v 1.7 '

/usr/libexec/java_homeA connection file that is represented in the Mac java_home .

?  ~  ll/usr/libexec/java_homelrwxr-xr-x  1 root  wheel    79B/16:39/usr/libexec/java_home System/library/frameworks/javavm.framework/versions/current/commands/java_home

Then in the execution

?  ~  mvn-vapache maven 3.2.1 (ea8b2b07643dbb1b84b6d16e1f08391b666bc1e9; 2014-02-15t01:37:52+08:00) maven home:/usr/ Local/cellar/maven/3.2.1/libexecjava version:1.7.0_71, Vendor:oracle Corporationjava home:/Library/Java/ Javavirtualmachines/jdk1.7.0_71.jdk/contents/home/jredefault LOCALE:ZH_CN, platform Encoding:utf-8os name: "Mac OS X" , Version: "10.10", Arch: "X86_64", Family: "Mac"

Then there is no such error in the Install project.
