问题 I am generating some classes with JDT. Afterwards I would like to format the whole ICompilationUnit, just as if I pressed Ctrl+Shift+F (Source > Format) in an open Editor without a selection. Any pointers for the API in JDT to format the source code programmatically is highly appreciated. Addition: I tried it like this, but the code isn't changed. What am I mssing? private void formatUnitSourceCode(ICompilationUnit targetUnit, IProgressMonitor monitor) throws JavaModelException {

问题 I have this method UpdateProperty: public void run(ObjectNavigatorModel model, String propertyKey, String propertyValue) { // get reference to CompilationUnit ICompilationUnit cu = model.getICompilationUnit(); try { cu.becomeWorkingCopy(null); } catch (JavaModelException e1) { e1.printStackTrace(); } // unit instance of CompilationUnit CompilationUnit unit = model.getCompilationUnit(); AST ast = unit.getAST(); ASTRewrite rewrite = ASTRewrite.create(ast); // get methods map MethodVisitor

问题 I have a code that removes all complex (not SimpleName expressions) from if s. It works fine and the code like if(obj.getSomeInt() > 10) { /* body */ } is converted to boolean value = obj.getSomeInt() > 10; if(value) { /* body */ } But before changing AST the call to resolveBinding() and resolveTypeBinding() for obj gives correct results, but after I get null for the both calls. Is that as designed? If yes, please tell how to fix that? My code: if(node instanceof IfStatement) { IfStatement

问题 There is a simple way to check if an annotation is present in a ICompilationUnit using Eclipse JDT? I tried to do the code below, but I will have to do the same thing for the super classes. IResource resource = ...; ICompilationUnit cu = (ICompilationUnit) JavaCore.create(resource); // consider only the first class of the compilation unit IType firstClass = cu.getTypes()[0]; // first check if the annotation is pressent by its full id if (firstClass.getAnnotation("java.lang.Deprecated").exists

问题 How do I run the plugin project under Resources [1] here: http://www.eclipse.org/articles/article.php?file=Article-JavaCodeManipulation%5FAST/index.html If I am not wrong, the project starting point is here public class ASTArticleActionDelegate implements IObjectActionDelegate -> public void run(IAction action) public void run(IAction action) { if (selection instanceof IStructuredSelection) { ICompilationUnit lwUnit = (ICompilationUnit) ((IStructuredSelection) selection).getFirstElement();

问题 I am writing a plug-in (ClassRefactoringPlugin) that examines source code in Eclipse 3.6.1. The plug-in contains a CallData class that examines a Java source file and figures out which Java elements are called from a method using JDT operations. I wrote a JUnit 4 test for this class that also resides in the ClassRefactoringPlugin project. When I ran it as a JUnit plug-in test, I got: Java Model Exception: Java Model Status [ClassRefactoringPlugin does not exist] What have I done wrong? The

问题 I have an eclipse Java project and want to get information like project source dir, classpaths, etc. My current implementation parses the .project file. But as I didn't find any official documentation describing the structure of the .project file, I have some concerns for the robustness of this approach. A more convenient and robust way would be to use JDT (headlessly) to load the project and get the relevant information from the IJavaProject object. Although the developer guide of JDT says

问题 I'm trying to create a project that depends on JDT core. I was using the entries in Maven central until I realized they were several years out of date. After poking around a little, I came across https://repo.eclipse.org. I found the repository I needed and added it: <repository> <id>eclipse</id> <name>Eclipse Repository</name> <url>https://repo.eclipse.org/content/groups/eclipse/</url> </repository> ... <dependency> <groupId>org.eclipse.jdt</groupId> <artifactId>org.eclipse.jdt.core<
