Re: [m2e-users] lifecycle-mapping for lesscss-maven-plugin

[Fred Bricon <fbricon@xxxxxxxxx>]

Alexis,

1 - Make sure your lifecycle-mapping definition is declared in the <pluginManagement> section of your pom.xml

2- The prepare-package phase is ignored by m2e. You should bind the less plugin execution to the process-resources phase instead

3- If you use m2e-wtp, I strongly suggest you change the output directory to target/m2e-wtp/web-resources/

I successfully ran the less plugin on incremental builds with the following configuration : 

<plugin>

<groupId>org.codehaus.mojo</groupId>

<artifactId>lesscss-maven-plugin</artifactId>

<version>1.0-beta-1</version>

<executions>

<execution>

<phase>process-resources</phase>

<goals>

<goal>compile</goal>

</goals>

</execution>

</executions>

<configuration>

<!-- No m2e connector for lesscss yet, working around by writing to 

source dir -->

<!-- Changes to .less won't be seen until after a maven build -->

<sourceDirectory>${project.basedir}/src/main/webapp/less</sourceDirectory>

<outputDirectory>${project.build.directory}/m2e-wtp/web-resources/less</outputDirectory>

<compress>true</compress>

</configuration>

</plugin>

Fred Bricon

Hello list,

 

I’m trying to get the lesscss-maven-plugin to run on incremental build. I experimented with modifying the plugin but hit some snags; also this requires m2e 1.1 which is not yet released. I understand I can get a similar effect with m2e 1.0 by adding config to my project’s pom.xml, which I have done:

 

                  <plugin>

                        <groupId>org.eclipse.m2e</groupId>

                        <artifactId>lifecycle-mapping</artifactId>

                        <version>1.0.0</version>

                        <configuration>

                              <lifecycleMappingMetadata>

                                    <pluginExecutions>

                                          <pluginExecution>

                                                <pluginExecutionFilter>

                                                      <groupId>org.codehaus.mojo</groupId>

                                                      <artifactId>lesscss-maven-plugin</artifactId>

                                                      <versionRange>[1.0-beta-1,)</versionRange>

                                                      <goals>

                                                            <goal>compile</goal>

                                                      </goals>

                                                </pluginExecutionFilter>

                                                <action>

                                                      <execute>

                                                            <runOnIncremental>true</runOnIncremental>

                                                      </execute>

                                                </action>

                                          </pluginExecution>

                                    </pluginExecutions>

                              </lifecycleMappingMetadata>

                        </configuration>

                  </plugin>

 

Unfortunately this does not seem to work. Here’s the plugin configuration I’m using:

 

                  <plugin>

                        <groupId>org.codehaus.mojo</groupId>

                        <artifactId>lesscss-maven-plugin</artifactId>

                        <version>1.0-beta-1</version>

                        <executions>

                              <execution>

                                    <phase>prepare-package</phase>

                                    <goals>

                                          <goal>compile</goal>

                                    </goals>

                              </execution>

                        </executions>

                        <configuration>

                              <!-- No m2e connector for lesscss yet, working around by writing to source dir -->

                              <!-- Changes to .less won't be seen until after a maven build -->

                              <sourceDirectory>${project.basedir}/WebContent</sourceDirectory>

                              <outputDirectory>${project.basedir}/WebContent</outputDirectory>

<!--                          <outputDirectory>${project.build.directory}/${project.build.finalName}</outputDirectory> -->

                              <compress>true</compress>

                        </configuration>

                  </plugin>

 

Please could anyone help me?

 

 

Thanks in advance,

Alexis
