Java. annotation classes are added to the jar package.

I don't know how these classes are compiled. These files are available in the classes directory during compilation.

Solution:

Add the following to the POM file:

<Build>
<Plugins>

<Plugin>
<Groupid> org. Apache. Maven. plugins </groupid>
<Artifactid> Maven-jar-plugin </artifactid>
<Version> 2.4 </version>
<Configuration>
<Excludes>
<Exclude> javax/** </exclude>
</Excludes>
</Configuration>
</Plugin>

</Plugins>
</Build>


Eliminate unnecessary files during the jar package. This also helps us eliminate unnecessary files.
