Java MacOSX 10.9.2上的Maven 3.2.1错误地使用了JRE 7，而不是JDK 7

我已尝试按照上的说明进行操作，但它们无法解决我的问题：-(

当我跑步时：

mvn clean install

mvn clean install -X

我得到以下问题：

我已经安装了Oracle的JDK7：

echo $JAVA_HOME
/Library/Java/JavaVirtualMachines/jdk1.7.0_55.jdk/Contents/Home

我添加到pom.xml中是因为maven决定使用1.5而不是1.7的源和目标：

            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.1</version>
                <configuration>
                    <source>1.7</source>
                    <target>1.7</target>
                </configuration>
            </plugin>

我看到它告诉我JRE正在被使用，而不是JDK。但我不能改变maven使用JDK而不是JRE-(

运行的输出：

mvn --version

javac -version

是:

运行的输出：

mvn --version

javac -version

是:

---

我在windows环境中也遇到过同样的错误。解决方案是将JAVA_HOME环境变量设置为JDK路径，而不是JRE路径。 这是：

JAVA\u HOME=C:\Program Files\JAVA\jdk1.7.0\u 55

路径=%JAVA\u HOME%\bin

请确保遵循针对OSX的maven安装说明。对于您来说，这可能是：

---

确保JAVA_HOME设置为JDK的位置，例如export JAVA_HOME=/usr/JAVA/jdk1.7.0_51，并且$JAVA_HOME/bin位于PATH环境变量中。

修复方法是从~/Library/JAVA/Extensions中的我的主目录中删除tools.jar

不知什么原因，我有一个JDK5版本的它躺在那里

---

如果您将其放在/Library/Java/Extensions的根文件夹中，您也可以检查并删除它。将上面发布的

mvn--version

编辑的输出包括您想要的输出

javac-version

？上面编辑的发布包括

javac-version

信息

javac 1.7.0_55
