Question

I am using jenkins with hudson cli through java. I want clean a particular directory before each build. Any idea ? I have provided the maven command clean package which clean target folder for each build. What i want is i want to clean some other directory before each build. How to do this ?

In jenkins i specified URL of maven project , Which ll download files to workspace when building. When i give clean package command, it clears target folder every time when building. There is another folder parallel to target folder. i want to clear that folder which is inside maven project.

In pom.xml add the profile tag like below

    <profiles>
        <profile>
            <id>ci</id>
            <activation>
                <activeByDefault>false</activeByDefault>
            </activation>
            <build>
                <plugins>
                    <plugin>
                        <artifactId>maven-clean-plugin</artifactId>
                        <version>2.5</version>
                        <executions>
                            <execution>
<id>default-clean</id>
<phase>pre-clean</phase>
<goals>
    <goal>clean</goal>
</goals>
                            </execution>
                        </executions>
                        <configuration>
                            <filesets xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<fileset>
    <directory>do_not_checkin/build</directory>
    <includes>
        <include>**/*</include>
                              </includes>
    <followSymlinks>false</followSymlinks>
                            </fileset>
                          </filesets>
                        </configuration>
                    </plugin>
                </plugins>
            </build>
        </profile>
    </profiles>

While executing commad just execute the maven command mvn -Pci clean.

Which uses the maven clean plugin to clear a particular directory, before each build starts.

We can package like mvn -Pci clean package.

After cleaning the directory , package phase is executed.
