从另一个项目创建一个Eclipse Java项目，编程式

Question

我想从另一个Java项目创建一个Java项目，使用Eclipse库中的一些脚本或Java方法（无论它是否存在）。此替代可以复制以前手动创建的项目。有没有办法呢？

谢谢。

Answer 1

我相信你可以利用IProject#copy（从IResource.copy继承）

Answer 2

添加到亚历山大·巴甫洛夫的答案，我发现一些额外的工作需要，除了复制的项目属性（如引用的项目）只是复制项目文件。

public static IProject copyProject(String projectName) throws CoreException { 
    IProgressMonitor m = new NullProgressMonitor(); 
    IWorkspaceRoot workspaceRoot = ResourcesPlugin.getWorkspace().getRoot(); 
    IProject project = workspaceRoot.getProject(projectName); 
    IProjectDescription projectDescription = project.getDescription(); 
    String cloneName = projectName + "_copy"; 
    // create clone project in workspace 
    IProjectDescription cloneDescription = workspaceRoot.getWorkspace().newProjectDescription(cloneName); 
    // copy project files 
    project.copy(cloneDescription, true, m); 
    IProject clone = workspaceRoot.getProject(cloneName); 
    // copy the project properties 
    cloneDescription.setNatureIds(projectDescription.getNatureIds()); 
    cloneDescription.setReferencedProjects(projectDescription.getReferencedProjects()); 
    cloneDescription.setDynamicReferences(projectDescription.getDynamicReferences()); 
    cloneDescription.setBuildSpec(projectDescription.getBuildSpec()); 
    cloneDescription.setReferencedProjects(projectDescription.getReferencedProjects()); 
    clone.setDescription(cloneDescription, null); 
    return clone; 
}
