使用Javaparser解析块/方法

Question

尝试解析

1. A Java method with // some sample comment in the function, and
2. Get method invocations in the function.

由于该方法具有// //我使用以下内容。方法

代码：

import com.github.javaparser.ast.body.*;
import com.github.javaparser.*;
import java.io.*;
import java.util.*;
import com.github.javaparser.ast.comments.BlockComment;
import com.github.javaparser.ast.expr.MethodCallExpr;
import java.nio.file.*;
import java.nio.charset.StandardCharsets;
import com.github.javaparser.ast.stmt.BlockStmt;

//Parsing the function
String snippet = "//this is a sample comment public void testFunction() //getting inputs 
{String String = new TestLayout(LAYOUT_TEXT, mTextPaint, mWidth, mAlign, mSpacingMult, 
mSpacingAdd);}";

String block = "{"+snippet+"}";

BlockStmt bs = StaticJavaParser.parseBlock(block);

//getting method invocations within the function
List<MethodCallExpr> mces = new ArrayList<>();
bs.walk(MethodCallExpr.class, mce-> mces.add(mce) );

错误：
