title: How to change Java version for Maven in IntelliJ?
body: <p>I'm new to both Maven and IntelliJ IDEA.</p>
  
  <p>I have a Maven project written in Java 8. Whenever I try to build it (Maven Projects window -> Lifecycle -> compile -> Run Maven Build) I get a series of compilation errors:</p>
  
  <pre><code>[ERROR] path/to/file.java:[26,52] lambda expressions are not supported in -source 1.5
  (use -source 8 or higher to enable lambda expressions)
  </code></pre>
  
  <p>Where am I supposed to change the value of the -source parameter? I tried adding it as an additional parameter in Settings -> Compiler - > Java Compiler, but I got the same results.</p>
  
  <p>The project's and module's language levels are both set to 8.0.</p>
  
  <p>I'm using Maven 3.2.3 and IntelliJ IDEA Community Edition 13.1.2.</p>
