如何在Eclipse之外的项目中使用Java Eclipse抽象语法树？（即不是eclipse插件）

如何在Eclipse之外的项目中使用Java Eclipse抽象语法树？（即不是eclipse插件）

给定一个Java 1.5文件，以下是我用来执行此 *** 作的代码。我对此很陌生，今天花了很多时间浏览并尝试使下面的代码正常工作。

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());     } }        }    }}

这需要以下库：
