java maven-compiler-plugin:3.1, javacTask: source release 1.7 requires target release 1.7

Question

I have a Java code that I want to build for Java 1.7.

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

But I receive the following error:

javacTask: source release 1.7 requires target release 1.7

The below debug outputs shows that target is 1.5:

How can I resolve this problem in NetBeans IDE?

Answer 1

You've spelt target wrong. It should be:

<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>

Answer 2

Change your terget with target and voilà :)

With Apache Maven 3.x is possible to write this as plain pom.xml properties.

More readable solution:

<properties>
  <maven.compiler.source>1.7</maven.compiler.source>
  <maven.compiler.target>1.7</maven.compiler.target>
</properties>

Answer 3

You have misspelled target - your element is named terget (not the second letter e). Just replace it with target, and you'll be good to go:

<target>1.7</target>
