Astparser parsing class files with enum enumeration methods

Problem description

Use ASTParser Parsing contains emum When enumerating class files of methods , The result of parsing is wrong . For example, after parsing the following file method The data contains the following four , among FULL_AMOUNT Is not a method, The corresponding row range is also inaccurate , As a result, we are in the impact area assessment , Evaluate the problems that the method has changed but cannot be found , Make the call link analysis and evaluation inaccurate .

STATUS
FULL_AMOUNT
TYPE
getNameByCode

Be resolved java Code

import lombok.Getter;


@Getter
public class DicTaskEnum {

    /**
     *  state 
     */
    @Getter
    public enum STATUS {
        /**
         *  unexecuted 
         */
        NO_EXECUTION(1, " unexecuted "),

        /**
         *  In execution 
         */
        EXECUTING(0, " In execution "),

        ;

        private final Integer code;

        private final String name;

        STATUS(Integer code, String name) {
            this.code = code;
            this.name = name;
        }


        public static String getNameByCode(Integer code) {
            for (STATUS typeEnum : STATUS.values()) {
                if (typeEnum.getCode().equals(code)) {
                    return typeEnum.getName();
                }
            }
            return null;
        }
    }

    /**
     *  state 
     */
    @Getter
    public enum TYPE {
        /**
         *  Total quantity 
         */
        FULL_AMOUNT(" Total quantity "),

        /**
         *  The incremental 
         */
        INCREMENTAL(" The incremental "),

        /**
         *  Specified scope 
         */
        SPECIFIED_RANGE(" Specified scope "),

        ;

        private final String name;

        TYPE(String name) {
            this.name = name;
        }

    }
}

AST Parsing code （ Not improved ）

        ASTParser parser = ASTParser.newParser(AST.JLS8);
        Map<String, String> options = JavaCore.getOptions(); //  add options  Can solve enum Wait for the problem of spanning tree parsing error 
        parser.setSource(javaSource.toCharArray());
        CompilationUnit cu = (CompilationUnit) parser.createAST(null);

Error after parsing cu data , You can see FULL_AMOUNT To become a void Method

import lombok.Getter;

@Getter public class DicTaskEnum {
  /** 
 *  state 
 */
  @Getter public enum STATUS;
{
  }
  private final Integer code;
  private final String name;
  void STATUS(  Integer code,  String name){
    this.code=code;
    this.name=name;
  }

  public static String getNameByCode(  Integer code){
    for (    STATUS typeEnum : STATUS.values()) {
      if (typeEnum.getCode().equals(code)) {
        return typeEnum.getName();
      }
    }
    return null;
  }
  /** 
 *  state 
 */
  @Getter public enum TYPE;
  /** 
 *  Total quantity 
 */
  void FULL_AMOUNT(){
  }
  private final String name;
  void TYPE(  String name){
    this.name=name;
  }
}

AST Parsing code （ After improvement , More options）

        ASTParser parser = ASTParser.newParser(AST.JLS8);
        Map<String, String> options = JavaCore.getOptions(); //  When parsing, add java1.8 Characteristics of options 
        options.put(JavaCore.COMPILER_SOURCE, JavaCore.VERSION_1_8);
        parser.setCompilerOptions(options);
        parser.setKind(ASTParser.K_COMPILATION_UNIT); //  Declare that what is passed in is java file 
        parser.setSource(javaSource.toCharArray());
        CompilationUnit cu = (CompilationUnit) parser.createAST(null);
        

The resolved cu data , This result is correct . Method 、 The line range is accurate
