Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.0.2:compile

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.0.2:compile (default-compile) on project mrlda: Compilation failure: Compilation failure:

[ERROR] /home/panwar/Downloads/Mr.LDA-master/src/main/java/cc/mrlda/polylda/TermReducer.java:[24,11] error: generics are not supported in -source 1.3

[ERROR] 
[ERROR] (use -source 5 or higher to enable generics)
[ERROR] /home/panwar/Downloads/Mr.LDA-master/src/main/java/cc/mrlda/TermReducer.java:[33,11] error: generics are not supported in -source 1.3

I'm using latest version of java.

Solved: The problem was with maven. I was using an older version(maven3.0.2) other things were correct.

You compile your code for java 1.3 and use generics, which was introduced in java 1.5. You have to change to java 1.5 or higher.

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

Your Maven is reading Java version as 1.6.0_65, Where as the pom.xml says the version is 1.7.

Try installing the required verison.

If already installed check your $JAVA_HOME environment variable, it should contain the path of Java JDK 7. If you don't find it, fix your environment variable.

also remove the lines:

 <fork>true</fork>
 <executable>${JAVA_1_7_HOME}/bin/javac</executable>

from the pom.xml

You may want to use a higher JDK-("Java"-) Version for the compiler plugin like:

<plugin>
      <artifactId>maven-compiler-plugin</artifactId>
      <version>3.2</version>
      <configuration>
        <source>1.7</source>
        <target>1.7</target>
        <showWarnings>true</showWarnings>
        <showDeprecation>true</showDeprecation>
      </configuration>
    </plugin>
