不在IntelliJ的maven目标目录下创建的类文件

Question

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.

[INFO] --- maven-compiler-plugin:3.1:compile (default-compile) @ PersonalizationFeeder ---

[INFO] Changes detected - recompiling the module!

[WARNING] File encoding has not been set, using platform encoding UTF-8, ie build is platform dependent!

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

[INFO] BUILD SUCCESS

What is the problem here? My pom.xml looks like this.

Problem solved...!! In one of the dependency jars, there is licenced jar and because of which it couldn't build properly. To solve the problem,I had to extract that particular dependency jar and remove .RSA,.DSA and *.SF files from META-INF/ dir and then make it jar using jar -cf command and then use this new jar as dependency. It worked fine for me. Thanks all.
