The Maven Clean Plugin will delete the target directory by default. You may configure it to delete additional directories and files. The following example shows how:
<build> [...] <plugin> <artifactId>maven-clean-plugin</artifactId> <version>2.6.1</version> <configuration> <filesets> <fileset> <directory>some/relative/path</directory> <includes> <include>**/*.tmp</include> <include>**/*.log</include> </includes> <excludes> <exclude>**/important.log</exclude> <exclude>**/another-important.log</exclude> </excludes> <followSymlinks>false</followSymlinks> </fileset> </filesets> </configuration> </plugin> [...] </build>
Note: The directory in the fileset is a relative path inside a project, in other words,
is equivalent to:
You could also define file set rules in a parent POM. In this case, the clean plugin adds the subproject basedir to the defined relative path.
