Answer 1

Instead of changing JDK versions and Maven versions, try this:

<plugin>
    <artifactId>maven-compiler-plugin</artifactId>
    <configuration>
        <source>1.7</source>
        <target>1.7</target>
    </configuration>
    <version>2.3.2</version>
</plugin>

Answer 2

Try to delete all your cache. When i deleted target folder, it works fine.

(Target folder is where maven puts all compiled code)

Answer 3

if your using jdk 1.6 kindly add this plugin entry to your pom.xml

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>2.0.2</version>
    <configuration>
        <source>1.6</source>
        <target>1.6</target>
        <compilerArgument>-Xlint:all</compilerArgument>
        <showWarnings>true</showWarnings>
        <showDeprecation>true</showDeprecation>
    </configuration>
</plugin>

Answer 4

Make sure to have the JDK version in your Build path and the version specified in the source tag match the same.

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>2.1</version>
    <configuration>
     **<source>1.7</source>**
       <target>1.7</target>
       <debug>true</debug>
    </configuration>
</plugin> `

I had the build path pointing to jdk 1.7 and "1.6" in the source tag, when I corrected the version to 1.7 in source tag the issue got resolved.

Execute mnv clean and mvn package.

Answer 5

Perhaps a version of maven war plugin is being used, which does not work with Java 7? As per this issue (which describes a similar problem), 2.1.1 version of maven war plugin should work.

Include the following in your pom.xml

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-war-plugin</artifactId>
    <version>2.1.1</version>
</plugin>

Answer 6

I had this problem with my eclipse Kepler. As soon as I moved to 4.4 (Luna) , all gone. Must be an issue with eclipse + maven embedded

I tried both JDK 1.7 and 1.8. No difference.
