Problem
Building a Maven project, hit following annotation error message in Maven output console.
[INFO] Compilation failure
E:\workspace\serlvetdemo\src\main\java\com\mkyong\AppServletContextListener.java:
[8,2] annotations are not supported in -source 1.3
(use -source 5 or higher to enable annotations)
@Override
Solution
Maven default is using JDK1.3 for the project compilation, building or packaging (mvn compile, install). Since JDK1.3 is not support annotation, if your project has annotation, you need to configure your Maven to use the latest JDK version. The solution is very simple, just include the Maven compiler plugin and specify the JDK version. For example,
<project ....>
<build>
<plugins>
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.3.2</version>
<configuration>
<source>1.6</source>
<target>1.6</target>
</configuration>
</plugin>
</plugins>
</build>
</project>
Above declaration tell Maven to use JDK 1.6.
How do I do this on intellij? Where can I find that xml file?
awesome

Thx man!!
I as well as my buddies appeared to be checking out the excellent hints found on your web site and suddenly developed a horrible feeling I had not expressed respect to the blog owner for those strategies. All of the women were as a result warmed to study all of them and already have definitely been using them. I appreciate you for being simply helpful and also for making a decision on such fantastic areas millions of individuals are really desperate to know about. My very own honest regret for not expressing gratitude to sooner.
sometimes this site seems more powerful than googleit principle 🙂
Thanks.
I struggled with that for more than a day. This really helped!
Thank you,
it solves the problem with my project which uses annotations and need JDK 1.5
Incredibly annoying problem. Thanks! 🙂
Hi, this helped with an issue I had. Locally everything worked fine, but after committing to Hudson build server the project build failed. Thanks for posting and I hope the “hudson” keyword will help people find the solution here faster.
Thanks man! This post was a great time saver for me.
