copied!<p>Below is the code I used to do this given a Java 1.5 file. I'm very new to this and spent today browsing around, and trying things out to get the code below working.</p> <pre><code>public void processJavaFile(File file) { String source = FileUtils.readFileToString(file); Document document = new Document(source); ASTParser parser = ASTParser.newParser(AST.JLS3); parser.setSource(document.get().toCharArray()); CompilationUnit unit = (CompilationUnit)parser.createAST(null); unit.recordModifications(); // to get the imports from the file List<ImportDeclaration> imports = unit.imports(); for (ImportDeclaration i : imports) { System.out.println(i.getName().getFullyQualifiedName()); } // to create a new import AST ast = unit.getAST(); ImportDeclaration id = ast.newImportDeclaration(); String classToImport = "path.to.some.class"; id.setName(ast.newName(classToImport.split("\\."))); unit.imports().add(id); // add import declaration at end // to save the changed file TextEdit edits = unit.rewrite(document, null); edits.apply(document); FileUtils.writeStringToFile(file, document.get()); // to iterate through methods List<AbstractTypeDeclaration> types = unit.types(); for (AbstractTypeDeclaration type : types) { if (type.getNodeType() == ASTNode.TYPE_DECLARATION) { // Class def found List<BodyDeclaration> bodies = type.bodyDeclarations(); for (BodyDeclaration body : bodies) { if (body.getNodeType() == ASTNode.METHOD_DECLARATION) { MethodDeclaration method = (MethodDeclaration)body; System.out.println("name: " + method.getName().getFullyQualifiedName()); } } } } } </code></pre> <p>This requires the following libraries:</p> <pre><code>commons-io-1.4.jar org.eclipse.jdt.core_xxxx.jar org.eclipse.core.resources_xxxx.jar org.eclipse.core.jobs_xxxx.jar org.eclipse.core.runtime_xxxx.jar org.eclipse.core.contenttype_xxxx.jar org.eclipse.equinox.common_xxxx.jar org.eclipse.equinox.preferences_xxxx.jar org.eclipse.osgi_xxxx.jar org.eclipse.text_xxxx.jar </code></pre>
