在eclipse插件开发中-路径相关

接口是org.eclipse.core.resources.IResource

1、Eclipse 中插件开发多语言的实现

为了使用 .properties 文件，需要在 META-INF/MANIFEST.MF 文件中定义：
      Bundle-Localization: plugin
这样就会自动加载 plugin.properties 文件(中文找 plugin_zh_CN.properties)
然后在 plugin.xml 文件中，将字符串替换为 %key 就可以了
建议先使用 Eclipse 的外部化字符串目录：

Bundle-Localization: OSGI-INF/l10n/plugin 

 

2、Eclipse 插件开发初始化隐藏某工具栏按钮

在网上找了好久都找不到解决办法，最后搜索 eclipse 安装目录，从它自己的插件里面找到样例了。样例来自 org.eclipse.jdt.ui/plugin.xml

 

 

<extension point="org.eclipse.ui.perspectiveExtensions">
   <perspectiveExtension  targetID="*">
      <!-- 注意这里的 id 是 action 或 command 的 id -->
<hiddenToolBarItem    id="org.eclipse.jdt.ui.actions.OpenProjectWizard">
      </hiddenToolBarItem>
   </perspectiveExtension> 

 

3、插件中获取 Eclipse 版本号

 

01.String sEclipseVersion = System.getProperty("osgi.framework.version");  4、插件中获取路径

 

// 得到插件所在的路径
Platform.asLocalURL(Platform.getBundle("your plugin ID").getEntry("")).getFile();

// 得到当前工作空间的路径
Platform.getInstanceLocation().getURL().getFile();

// 得到当前工作空间下的所有工程
ResourcesPlugin.getWorkspace().getRoot().getProjects();

// 得到某 PLUGIN 的路径:
Platform.getBundle("mypluginid").getLocation().
// eclipse采用osgi后好像还可以:
Activator.getDefault().getBundle().getLocation(); //前提是这个插件有Activator这个类.这个类继承了ECLIPSE的Plugin类
// eclipse采用osgi前好像好像是:
MyPlugin.getDefault().getBundle().getLocation(); //前提是这个插件有MyPlugin这个类.这个类继承了ECLIPSE的Plugin类

// 得到工作区路径:
Platform.getlocation();
// 或 ResourcesPlugin.getWorkspace(); 好像 Platform.getInstanceLocation() 也可行

// 得到ECLIPSE安装路径
Platform.getInstallLocation();

// 从插件中获得绝对路径：
AaaaPlugin.getDefault().getStateLocation().makeAbsolute().toFile().getAbsolutePath();

// 通过文件得到 Project：
IProject project = ((IFile)o).getProject();

// 通过文件得到全路径：
String path = ((IFile)o).getLocation().makeAbsolute().toFile().getAbsolutePath();

// 得到整个Workspace的根：
IWorkspaceRoot root = ResourcesPlugin.getWorkspace().getRoot();

// 从根来查找资源：
IResource resource = root.findMember(new Path(containerName));

// 从Bundle来查找资源：
Bundle bundle = Platform.getBundle(pluginId);
URL fullPathString = BundleUtility.find(bundle, filePath);

// 得到 Appliaction workspace：
Platform.asLocalURL(PRODUCT_BUNDLE.getEntry("")).getPath()).getAbsolutePath();

// 得到 runtimeworkspace：
Platform.getInstanceLocation().getURL().getPath();

// 从编辑器来获得编辑文件
IEditorPart editor = ((DefaultEditDomain)(parent.getViewer().getEditDomain())).getEditorPart();
IEditorInput input = editor.getEditorInput();
if(input instanceof IFileEditorInput)
{
IFile file = ((IFileEditorInput)input).getFile();
}

// 获取插件的绝对路径：
FileLocator.resolve(BuildUIPlugin.getDefault().getBundle().getEntry("/")).getFile();

5、添加myeclipse JAVAEE Library 与User Library

IClasspathEntry myEclipseJAVAEE5 =JavaCore.newContainerEntry(new Path("melibrary.com.genuitec.eclipse.j2eedt.core.MYECLIPSE_JAVAEE_5_CONTAINER"));
IClasspathEntry myEclipseUCITPortletDev =JavaCore.newContainerEntry(new Path("org.eclipse.jdt.USER_LIBRARY/UCITPortletDev"));

6、利用Ifile向项目中写文件

 

    /**
     * jar文件输入流
     * @param path
     * @return
     */
    private InputStream fileInput(File path){
       
        try {
            FileInputStream fis=new FileInputStream(path);
            return fis;
        } catch (FileNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        return null;
    }
   
    /**
     * Adds a new file to the project.
     *
     * @param container
     * @param path
     * @param contentStream
     * @param monitor
     * @throws CoreException
     */
    private void addFileToProject(IContainer container, Path path,
            InputStream contentStream, IProgressMonitor monitor)
            throws CoreException {
        final IFile file = container.getFile(path);

        if (file.exists()) {
            file.setContents(contentStream, true, true, monitor);
        } else {
            file.create(contentStream, true, monitor);
        }

    }
 

        //写入自动生成portlet环境的jar包
        IContainer container = (IContainer) project;
        IProgressMonitor monitor = new NullProgressMonitor();
        Path autoJar=new Path(WEBROOT+FILESEPARATOR+WEBINF+FILESEPARATOR +LIB+FILESEPARATOR+"UcitPortletDev.jar");    //项目路径
        InputStream jarIS=fileInput(new File("d:/PortletAuto.jar"));    //本地文件路径
       
        //写入自动生成portlet环境的xml配置文件
        Path autoConfigXML=new Path("src"+FILESEPARATOR+"service_portlet.xml");    //项目路径
        InputStream XMLIS=fileInput(new File(selectConfigPath));    //本地文件路径
       
        try {
            addFileToProject(container,autoJar,jarIS,monitor);    //Jar
            monitor = new NullProgressMonitor();
            addFileToProject(container,autoConfigXML,XMLIS,monitor);    //XML
        } catch (CoreException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }finally{
            if (jarIS!=null){
                jarIS.close();
            }
            if (XMLIS!=null){
                XMLIS.close();
            }
        }
 

7、获取Eclipse当前项目

import org.eclipse.jdt.internal.ui.packageview.PackageFragmentRootContainer;

public static IProject getCurrentProject(){  
        ISelectionService selectionService =   
            Workbench.getInstance().getActiveWorkbenchWindow().getSelectionService();  
  
        ISelection selection = selectionService.getSelection();  
  
        IProject project = null;  
        if(selection instanceof IStructuredSelection) {  
            Object element = ((IStructuredSelection)selection).getFirstElement();  
  
            if (element instanceof IResource) {  
                project= ((IResource)element).getProject();  
            } else if (element instanceof PackageFragmentRootContainer) {  
                IJavaProject jProject =   
                    ((PackageFragmentRootContainer)element).getJavaProject();  
                project = jProject.getProject();  
            } else if (element instanceof IJavaElement) {  
                IJavaProject jProject= ((IJavaElement)element).getJavaProject();  
                project = jProject.getProject();  
            }  
        }   
        return project;  
    }  

 

  ISelectionService selectionService = Workbench.getInstance()
    .getActiveWorkbenchWindow().getSelectionService();
  ISelection selection = selectionService.getSelection();

 

 

public static IProject getProject(){   
        IProject project = null;   
          
        //1.根据当前编辑器获取工程   
        IEditorPart part = getActiveEditor();   
       if(part != null){   
          Object object = part.getEditorInput().getAdapter(IFile.class);   
          if(object != null){   
             project = ((IFile)object).getProject();   
           }   
     }   
          
       if(project == null){   
            ISelectionService selectionService =      
                    Workbench.getInstance().getActiveWorkbenchWindow().getSelectionService();     
         ISelection selection = selectionService.getSelection();     
            if(selection instanceof IStructuredSelection) {     
               Object element = ((IStructuredSelection)selection).getFirstElement();     

              if (element instanceof IResource) {     
                   project= ((IResource)element).getProject();     
              } else if (element instanceof PackageFragmentRootContainer) {     
                    IJavaProject jProject =      
                      ((PackageFragmentRootContainer)element).getJavaProject();     
                  project = jProject.getProject();     
                } else if (element instanceof IJavaElement) {     
                   IJavaProject jProject= ((IJavaElement)element).getJavaProject();     
                    project = jProject.getProject();     
              } else if(element instanceof EditPart){   
                    IFile file = (IFile) ((DefaultEditDomain)((EditPart)element).getViewer().getEditDomain()).getEditorPart().getEditorInput().getAdapter(IFile.class);   
                  project = file.getProject();   
              }    
           }      
      }   
          
      return project;   
    }
