I build my project with maven, and the pom.xml is the following:

```
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    </parent>

    <properties>

    <build>
        <plugins>
            <plugin>

            </plugin>
        </plugins>
    </build>
</project>

```

And I run mvn package with this pom.xml, it shows some error message:

```

```

but I already set $JAVA\_HOME before.

```
➜ ~ echo $JAVA_HOME
/Library/Java/JavaVirtualMachines/jdk1.8.0_151.jdk/Contents/Home
➜ ~ which java
/usr/bin/java
➜ ~ which javac
/usr/bin/javac

```

How to resolve this issue ? I found another same [issue](https://discuss.elastic.co/t/elasticsearch-2-3-5-maven-build-error-with-enforce-plugin-java-home/67188/2) here but there is no answer.

Find the answer, Idea does not read the env variable correctly, use `launchctl setenv JAVA_HOME /Library/Java/JavaVirtualMachines/jdk1.8.0_151.jdk/Contents/Home` could fix it.

Please close this issue. Thanks
