java - ASTParser 依赖项

Question

我正在尝试在 this 的帮助下学习 ASTParser教程。当我编译第一段代码时:
ASTParser parser = ASTParser.newParser(AST.JLS2);
parser.setSource("".toCharArray());
CompilationUnit unit = (CompilationUnit) parser.createAST(null);
unit.recordModifications();
AST ast = unit.getAST();
我收到此错误:

Source non found. The JAR of this class file belongs to container 'Plug-in Dependencies' which does not allow modifications to source attachments on its entries.

我能做什么？

根据 this ，你应该包括这些 jar 文件:

org.eclipse.core.contenttype.jar

org.eclipse.core.jobs.jar

org.eclipse.core.resources.jar

org.eclipse.core.runtime.jar

org.eclipse.equinox.common.jar

org.eclipse.equinox.preferences.jar

org.eclipse.jdt.core.jar

org.eclipse.osgi.jar
