eclipse-jdt

I have an Eclipse CDT environment up and running and customised just the way I like it. I'm also going to be heavily dealing with Java. I don't want to install a separate version of Eclipse just to get the Java features, as I'll be switching between C -> C++ -> ADA -> Java quite often. Because of this I'd like the one IDE to support all the languages. At the moment I've got C/C++ and Ada working together (CDT + GNAT workbench). How can I get the Eclipse Java support installed with out installing Eclipse from scratch again? I've had both installed together without problems. In fact I had the

I am trying to modify source code using eclipse plugin, JDT and AST (Abstract Syntax Tree). I can read all Java files and make operation on all those file, But when i am saving those changes (Edits) in to files using TextEdit edits = rewriter.rewriteAST(); // apply the text edits to the compilation unit edits.apply(document); iCompilationUnit.getBuffer().setContents(document.get()); It only make changes in file those are open in eclipse in unsaved mode. Rest of files are not affected. Find my code snippet below: CompilationUnit cu = parse(iCompilationUnit); MethodVisitor visitor = new

I am writing unit tests for my plugin that makes use of IType and IMethod interfaces from JDT. To write unit tests I would need to instantiate such interfaces. Answer to this question shows how to create AST model, but I don't know how to convert it into Java model? My code looks like this: String source = "package com.test\n" + "\n" + "import com.test.something;" + "\n" + "public class Class{\n" + "int sum(int a, int b)\n" + "}\n"; ASTParser parser = ASTParser.newParser(AST.JLS4); parser.setSource(source.toCharArray()); CompilationUnit unit = (CompilationUnit) parser.createAST(null); So I

I have the following code IJavaProject targetProject = null; IWorkspaceRoot root = ResourcesPlugin.getWorkspace().getRoot(); for (IProject project : root.getProjects()) { if (project.getName().equals(projName)) { try { if (project.hasNature("org.eclipse.jdt.core.javanature")) { targetProject = (IJavaProject) project; } } catch( ... ) { // etc ... } What I am trying to do is essentially return a project that matches a particular name as an IJavaProject. As you can see, I check to ensure that the project in question has a java nature by calling: if (project.hasNature("org.eclipse.jdt.core

I've noticed eclipse JDT uses void as a primitive type . Can this be considered correct? Pops I find that, in cases like this, you can't beat going to the Java Language Specification. It is pretty clear about the fact that void is not a primitive. First off, void is not in the list of primitive types . Later on, the JLS explicitly states: the Java programming language does not allow a "cast to void" — void is not a type http://java.sun.com/docs/books/jls/third_edition/html/statements.html#5989 (emphasis mine) Furthermore, void appears in the list of keywords , not the list of literals. The

What I am trying to do is to get a class name of a method. For example, I want to get a class of 'until' and 'search' methods. Here are the code. Query query = new Query(queryStr).until(dateStr); QueryResult queryResult = twitter1.search(query); From these examples, the expected results are Query.until and SearchResource.search . But when I used this code below, I only got until and search , no class name. If I use MethodInvocation.getExpression(), I can get the names of the instances:new Query(queryStr) and twitter1. But they are not what I really want. ASTParser parser = ASTParser.newParser
