class files not created under maven target directory in IntelliJ
<p>I have created a simple maven project to create shaded jar. I built it using mvn clean compile .It creates jar file but after extracting it i don't see .class files corresponding to my project java source files. I see clearly below message when i build but don't see any .class files under target dir.</p>

<p>[INFO] --- maven-compiler-plugin:3.1:compile (default-compile) @ PersonalizationFeeder ---</p>

<p>[INFO] Changes detected - recompiling the module!</p>

<p>[WARNING] File encoding has not been set, using platform encoding UTF-8, i.e. build is platform dependent!</p>

<p>[INFO] Compiling 10 source files to Documents/PersonalizationFeeder/target/classes
[INFO] ------------------------------------------------------------------------</p>

<p>[INFO] BUILD SUCCESS</p>

<p>What is the problem here?  My pom.xml looks like this.</p>
