[英]I'm having an issue with using ASTParser in eclipse
我正在尝试在 eclipse 中使用 ASTParser,但面临 NoClassDefFoundError。 我已经遵循了一些指南并导入了相关的 9 jars。 以下是详细信息:
package test_JDT;
import java.io.BufferedInputStream;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import org.eclipse.jdt.core.dom.AST;
import org.eclipse.jdt.core.dom.ASTParser;
import org.eclipse.jdt.core.dom.CompilationUnit;
// import org.eclipse.equinox.common.*;
// import org.eclipse.core.jobs;
class tester {
public static void main(String[] args) {
// TODO Auto-generated method stub
System.out.println("hello ast parser");
String javaFilePath = "C:\\Users\\tabzhang\\eclipse-workspace\\test_JDT\\src\\test_JDT/classdemo.java";
byte[] input = null;
try {
BufferedInputStream bufferedInputStream = new BufferedInputStream(new FileInputStream(javaFilePath));
input = new byte[bufferedInputStream.available()];
bufferedInputStream.read(input);
bufferedInputStream.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
String str = new String(input);
System.out.println(str);
ASTParser astParser = ASTParser.newParser(AST.JLS3);
astParser.setSource(new String(input).toCharArray());
astParser.setKind(ASTParser.K_COMPILATION_UNIT);
CompilationUnit result = (CompilationUnit) (astParser.createAST(null));
}
}
我应该如何让代码运行良好?
在Project > Properties: Java Build Path中,标签Libraries将所有JARs 从Modulepath移动到Classpath 。
