[m2e-users] Programmatically Build Maven Project

[Daniel Johnson <danijoh2@xxxxxxxxx>]

Hello m2e users,

I have been trying to build a maven project that needs to have tycho configurators executed programmatically but with not much luck. Usually I can use this code to build a maven pom.xml file:

public static BuildSummary runMaven(IFile pomFile, List<String> goals, IProgressMonitor monitor) throws CoreException{

        if (monitor == null){

            monitor = new NullProgressMonitor();

        }

        try {

            monitor.beginTask("Building: " + pomFile.getName(), 3);

            MavenProjectManager projectManager = MavenPlugin.getDefault().getMavenProjectManager();

            IMaven maven = MavenPlugin.getDefault().getMaven();

            IMavenProjectFacade facade = projectManager.create(pomFile, true, new SubProgressMonitor(monitor, 1));

            ResolverConfiguration config = facade.getResolverConfiguration();

            MavenExecutionRequest request = projectManager.createExecutionRequest(pomFile, config, new SubProgressMonitor(monitor, 1));

            request.getUserProperties().setProperty("m2e.version", MavenPlugin.getVersion());

            request.setGoals(goals);

            MavenPlugin.getDefault().getConsole().showConsole();

            MavenExecutionResult result = maven.execute(request, new SubProgressMonitor(monitor, 1));

            if ( result.hasExceptions()){

             // Throw CoreException

            }

            

            BuildSummary summary = result.getBuildSummary(result.getProject());

            return summary;

        } 

        finally {

            monitor.done();

        }

}

But when I try this on a project that needs tycho conifurations ran I found this doesn't work. I found that the m2eclipse auto builder was also failing on my project in the same way and after doing some googling I realized I need this in my project pom for the m2eclipse auto builder to work correctly:

<profiles>

    <profile>

      <id>m2e</id>

      <activation>

        <property>

          <name>m2e.version</name>

        </property>

      </activation>

      <build>

        <plugins>

          <plugin>

            <groupId>org.maven.ide.eclipse</groupId>

            <artifactId>lifecycle-mapping</artifactId>

            <version>0.10.0</version>

            <configuration>

              <mappingId>customizable</mappingId>

              <configurators>

                <configurator id="org.maven.ide.eclipse.jdt.javaConfigurator" />

                <configurator id="org.maven.ide.eclipse.modello.modelloConfigurator" />

                <configurator id="org.maven.ide.eclipse.plexus.annotations.plexusConfigurator" />

                <configurator id="org.maven.ide.eclipse.mavenarchiver.pomProperties" />

                <configurator id="maven-bundle-plugin" />

              </configurators>

              <mojoExecutions>

                <mojoExecution>org.apache.maven.plugins:maven-resources-plugin::</mojoExecution>

                <mojoExecution>org.apache.maven.plugins:maven-plugin-plugin::descriptor</mojoExecution>

              </mojoExecutions>

            </configuration>

          </plugin>

          <plugin>

            <groupId>org.sonatype.tycho</groupId>

            <artifactId>tycho-maven-plugin</artifactId>

            <version>0.7.0</version>

            <extensions>true</extensions>

          </plugin>

        </plugins>

      </build>

    </profile>

</profiles>

However, the function I have still does not work. I even tried the following two lines to be sure that the m2e profile would be picked up.

ResolverConfiguration config = facade.getResolverConfiguration();

config.setActiveProfiles("m2e"); // Added this, but when execute runs it says it can't be activated because it does not exist

MavenExecutionRequest request = projectManager.createExecutionRequest(pomFile, config, new SubProgressMonitor(monitor, 1));

request.getUserProperties().setProperty("m2e.version", MavenPlugin.getVersion()); // Added this in hopes of activating the m2e profile in the pom

But this doesn't seem to help either. Is there a better way to do this? Can anyone point me to the m2eclipse auto builder code so I can see what it is doing differently?

m2e version = 0.10.2, tycho=0.4.3

I have also tried this code with the same results:

IMaven maven = MavenPlugin.getDefault().getMaven();

MavenPlugin.getDefault().getConsole().showConsole();

File file = new File(pomFile.getLocationURI());

File projectDirectory = new File(pomFile.getProject().getLocationURI());

MavenExecutionRequest request;

request = maven.createExecutionRequest(monitor);

request.setBaseDirectory( projectDirectory );

request.setPom(file);

request.setGoals(goals);

request.setShowErrors(true);

MavenExecutionResult result = maven.execute(request, monitor);

Thanks in advance,

Daniel
