title: Maven 3.8.0 Compiler - Fatal error compiling: release version 11 not supported
body: <p>I'm unable to build using Java 11 with the latest version of the maven-compiler-plugin.</p>
  
  <p>pom.xml:</p>
  
  <pre><code>&lt;build&gt;

          &lt;plugin&gt;

      &lt;plugins&gt;

  <p>when I try to build using Maven:</p>

  <p>Here are the Maven and Java versions which I am using:</p>
  
  <pre><code>➜  mvn -version
  Apache Maven 3.5.2
  Maven home: /usr/share/maven
  Java version: 10.0.1, vendor: Oracle Corporation
  Java home: /usr/lib/jvm/java-11-openjdk-amd64
  Default locale: en_GB, platform encoding: UTF-8
  OS name: "linux", version: "4.15.0-29-generic", arch: "amd64", family:     "unix"
  ➜  /usr/lib/jvm/java-11-openjdk-amd64/bin/java -version
  openjdk version "10.0.1" 2018-04-17
  OpenJDK Runtime Environment (build 10.0.1+10-Ubuntu-3ubuntu1)
  OpenJDK 64-Bit Server VM (build 10.0.1+10-Ubuntu-3ubuntu1, mixed mode)
  </code></pre>
  
  <p>Could Java 11 identifying itself as "10.0.1" be causing the problem? If I modify my pom.xml to <code>&lt;release&gt;10&lt;/release&gt;</code> then it builds with no issue, even though I do not have Java 10 installed.</p>
  
  <pre><code>➜  ~ /usr/lib/jvm/java-11-openjdk-amd64/bin/javac -version
  javac 10.0.1 
  
  ➜ javac --release 11 SomeClass.java
  javac: release version 11 not 
  supported Usage: javac &lt;options&gt; &lt;source files&gt;
  use --help for a list of possible options
  </code></pre>
  
  <p>I think this is an issue with the Ubuntu <code>openjdk-11-jdk</code> package:</p>
  
  <pre><code>➜  ~ sudo apt install openjdk-11-jdk
  Reading package lists... Done

  openjdk-11-jdk is already the newest version (10.0.1+10-3ubuntu1).
  0 to upgrade, 0 to newly install, 0 to remove and 2 not to upgrade.
