eclipse插件开发_遇到问题总结

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
<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

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;???
????}
