Eclipse从.java文件创建CompilationUnit [英] Eclipse create CompilationUnit from .java file

问题描述

如何将.java文件加载到CompilationUnit？例如，让我说我现在的项目中有一个A.java文件。我想将其加载到CompilationUnit中，然后将其传递给ASTParser。它不是一个选项，只是加载它作为一个纯文本，因为似乎在这种情况下，我不会得到在AST中的绑定信息。

How can I load a .java file into a CompilationUnit? For example, lets say I have a A.java file in my current project. I would like to load it into a CompilationUnit and then pass it to the ASTParser. It is not an option just to load it as a plain text since it seems that in that case I will not get the binding information in the AST.

推荐答案

您可以使用 jdt 和 eclipse core 库加载项目。

You can load the projects using jdt and eclipse core libraries.

使用以下代码可以加载工作区中的所有项目。

Using the following code you can load all the projects in the workspace.

IWorkspace workspace = ResourcesPlugin.getWorkspace();
IWorkspaceRoot root = workspace.getRoot();
// Get all projects in the workspace
IProject[] projects = root.getProjects();

然后你可以获取包，依次获取java文件。

Then you can get packages and in turn the java files.

IPackageFragment[] packages = JavaCore.create(project).getPackageFragments();
IPackageFragment mypackage = packages.get(0); // implement your own logic to select package
ICompilationUnit unit = mypackage.getCompilationUnits();

然后，您可以使用此ICompilationUnit对象获取CompilationUnit

Then you can use this ICompilationUnit object for getting the CompilationUnit

ASTParser parser = ASTParser.newParser(AST.JLS3); 
parser.setKind(ASTParser.K_COMPILATION_UNIT);
parser.setSource(unit);
parser.setResolveBindings(true);
CompilationUnit cUnit = parser.createAST(null);

此CompilationUnit对象可以传递给ASTParser。

This CompilationUnit object can be passed on to the ASTParser.
