java - invalid target release: 1.7

Question

I have seen similar questions, but haven't yet found the answer.

Using maven compile, I get:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.0:compile (default-compile) on project api: Fatal error compiling: invalid target release: 1.7 -> [Help 1]

Here is the pom.xml:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.0</version>
    <configuration>
        <source>1.7</source>
        <target>1.7</target>
        <encoding>UTF-8</encoding>
    </configuration>
</plugin>

Javac version:

javac 1.7.0_25

Java version:

java version "1.7.0_25"
Java(TM) SE Runtime Environment (build 1.7.0_25-b15)
Java HotSpot(TM) 64-Bit Server VM (build 23.25-b01, mixed mode)

Any idea what it could be?

You need to set JAVA_HOME to your jdk7 home directory, for example on Microsoft Windows:

• "C:Program FilesJavajdk1.7.0_40"

or on OS X:

• /Library/Java/JavaVirtualMachines/jdk1.7.0_40.jdk/Contents/Home
