Eclipse 插件开发遇到问题心得总结

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"));
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);
}
}
* 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();
}
}
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;
}
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;
}
