Problems running Java 8 TestNG inside IntelliJ

I am writing a Maven application using OpenJDK 1.8 and running tests using TestNG.

When I run Maven from the command line everything works fine, but when I try to run the test inside IntelliJ, then the make process is displaying the following error:

java: javacTask: source release 8 requires target release 1.8

I have the project settings pointing to the 1.8 JDK and Project Language Level 8.

Inside Maven I have the following block (which I am guessing is not getting called yet as it seems to be the make causing the problem)

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>2.3.2</version>
    <configuration>
      <source>1.8</source>
      <target>1.8</target>
    </configuration>
  </plugin>

I have even configured the Maven Runner JRE to point to the 1.8 JDK.

I just don't seem to be able to get IntelliJ 12.0.4 to run the tests properly

Am I missing something?

For me, I needed to go File > Project Structure > Modules. Half of my modules had their "module SDK" field set to the wrong thing (not Project Default as they should have been).

Xetius' answer didn't work for me in IntelliJ 14.1.2

In the end I found the section in .idea/misc.xml

<component name="ProjectRootManager" version="2" languageLevel="JDK_1_6" assert-keyword="true" jdk-15="true" project-jdk-name="1.7" project-jdk-type="JavaSDK">
   <output url="file://$PROJECT_DIR$/out" />
</component>

I ended up with:

<component name="ProjectRootManager" version="2" languageLevel="JDK_1_8" default="false" assert-keyword="true" jdk-15="true" project-jdk-name="1.8" project-jdk-type="JavaSDK">
    <output url="file://$PROJECT_DIR$/out" />
</component>

There is another way to make it. Go to Files->Other Settings->Type "javac" in the search bar -> change the JDK default to "1.8" or any version you target.

After the hint from CrazyCoder it turns out that .idea/compiler.xml had the following section in it

<bytecodeTargetLevel> 
    <module name="game" target="1.7" /> 
</bytecodeTargetLevel>

I changed this to:

<bytecodeTargetLevel> 
    <module name="game" target="1.8" /> 
</bytecodeTargetLevel>

and it worked
