  1. POcompiling and running java8/jdk8 code in netbeans - Uncompilable source code
    text
    copied!<p>After playing with preview of <a href="http://jdk8.java.net/lambda/" rel="nofollow">JDK 1.8</a> in notepad and compiling files from command line, I thought I would try with netbeans and see what happens.</p> <p>I have successfully added JDK 1.8 and changed the following settings:</p> <blockquote> <p>properties -> libraries -> java platform: <strong>JDK 1.8</strong> </p> <p>properties -> sources -> Source/Binary format: <strong>JDK 8</strong></p> </blockquote> <p>When I <code>Clean and build</code> the project from netbeans, it builds successfully. And suggests to execute project with following command:</p> <blockquote> <p>javac 1.8.0-ea</p> <p>To run this application from the command line without Ant, try:</p> <p><strong>C:\Program Files\Java\jdk1.8.0/bin/java -jar "C:\Java8\JavaBacon\dist\JavaBacon.jar"</strong></p> </blockquote> <p>and it runs just fine from command line!</p> <p>But when I try to <code>Run</code> the project, I get following exception:</p> <pre><code>Exception in thread "main" java.lang.RuntimeException: Uncompilable source code - Erroneous tree type: &lt;any&gt; </code></pre> <p>It can build, but can't run?? </p> <p>My current workaround for this, is just to put the Java8 code in separate <code>Java Class Library</code> and call it from main project, since it can build the library. Obviously when using java8 features, you get red squiggles, lack of intellisense and autoformatting changes <code>-&gt;</code> to <code>- &gt;</code>, but it builds! ( very nice :D )</p> <p>But what is the reason for not being able to <code>Run</code> the project?</p> <h2>UPDATE:</h2> <p>The exception goes away when disabling <code>Compile On Save</code> setting under:</p> <blockquote> <p>Properties > Build > Compiling</p> </blockquote> <p><a href="http://netbeans.org/bugzilla/show_bug.cgi?id=199293" rel="nofollow">http://netbeans.org/bugzilla/show_bug.cgi?id=199293</a></p>
