This plugin contains additional checks for checkstyle. It is packaged as an eclipse plugin, so it can be used with the Eclipse Checkstyle Plugin by just putting the invesdwin-checkstyle-plugin.jar inside eclipse/dropins/ or /home/$USER/.eclipse/<current>/dropins or /home/$USER/snap/eclipse/current/amd64/dropins depending on the installation method.

Releases and snapshots are deployed to this maven repository:

https://invesdwin.de/repo/invesdwin-oss-remote/

Dependency declaration:

<dependency>
	<groupId>de.invesdwin</groupId>
	<artifactId>invesdwin-checkstyle-plugin</artifactId>
	<version>1.0.4</version>
</dependency>

Currently this plugin contains the following checks:

• de.invesdwin.checkstyle.InternalImportCheck: with this you can enforce the rule that internal packages are not used outside of your module. You can also change the name of the package by using the internalPackageName property.

<module name="de.invesdwin.checkstyle.InternalImportCheck">
	<property name="internalPackageName" value="internal" />
</module>

• de.invesdwin.checkstyle.NotNullParameterAnnotationCheck: Findbugs can parse @Nonnull, but not @NotNull in parameters correctly, this check verifies that the developer does not use the wrong annotation.

<module name="de.invesdwin.checkstyle.NotNullParameterAnnotationCheck" />
