如何以编程方式将maven性质添加到工作室项目中

Question

我想通过java代码将maven性质添加到我现有的工作室项目中.在eclipse中,我们可以通过右键单击 - > configure-> convert to Maven选项来实现.我如何通过java代码调用它？我的方案是,我已经为项目添加了 右键单击- >菜单 - >生成POM选项,点击此项我将为项目生成POM文件,然后我想在同一个单击中添加maven性质.我可以从我的java代码中调用eclipses默认代码转换为maven吗？

我找到了解决方案.我们可以将maven性质添加到项目中,如下所示 - 我有一个eclipse项目.

import org.eclipse.core.resources.ICommand;
import org.eclipse.core.resources.IProject;
import org.eclipse.core.resources.IProjectDescription;
import org.eclipse.core.runtime.NullProgressMonitor;
import org.eclipse.ui.IWorkbenchWindow;

private void addMavenNature( IProject project){
   IProjectDescription desc = project.getDescription();

   String[] prevNatures = desc.getNatureIds(); //it takes all previous natures of project i.e studioNature,javanature
   String[] newNatures = new String[prevNatures.length + 1];

   System.arraycopy(prevNatures, 0, newNatures, 0, prevNatures.length);

   newNatures[prevNatures.length] = "org.eclipse.m2e.core.maven2Nature"; //add maven nature to the project
   desc.setNatureIds(newNatures);

   project.setDescription(desc, new NullProgressMonitor());

   ICommand[] commands = desc.getBuildSpec();
   List<ICommand> commandList = Arrays.asList( commands );
   ICommand build = new BuildCommand();
   build.setBuilderName("org.eclipse.m2e.core.maven2Builder"); //add maven builder to the project
   List<ICommand> modList = new ArrayList<>( commandList );
   modList.add( build );
   desc.setBuildSpec( modList.toArray(new ICommand[]{}));
}
