java - Maven项目安装: invalid target release: 1. 7错误

Question

当我尝试使用 Maven 安装项目时遇到此错误。我读了很多帖子，说这个错误是因为maven正在使用另一个版本的java，但这不是我的情况(我认为)，因为我运行的每个命令都说使用的版本是java 1.7。

这是终端的结果:

Maven installation error:
Failure executing javac, but could not parse the error:
javac: invalid target release: 1.7
Usage: javac <options> <source files>
use -help for a list of possible options

mvn -version 的输出

Apache Maven 3.1.1 (0728685237757ffbf44136acec0402957f723d9a; 2013-09-17 12:22:22-0300)

pom.xml(编译器插件部分):

<plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>2.3.2</version>
                <configuration>
                    <source>1.7</source>
                    <target>1.7</target>
                </configuration>
            </plugin>

在我看来一切都很好，但不断出现错误。

将 maven-compiler-plugin 版本更新为 3.3:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.3</version> <!--  HERE  -->
    <configuration>
        <source>1.7</source>
        <target>1.7</target>
    </configuration>
</plugin>

JAVA_HOME是如何设置的？

Java home: /Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home/jre

看起来您需要将其更正为 /Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/

Why I am not able to see the JAVA_HOME path on my MAC OS X 10.11?
