在有关JavaParser的另一个线程中,您写道:“它不应具有任何依赖关系”。但是JavaParser具有对特殊ParseException的依赖:
在JavaParser中,line 205: throw new ParseException(ioe.getMessage())
构造函数ParseException(String)未定义
-添加参数以匹配ParseException(String,int)
例如。 java.text.ParseException(和其他三个)还有一个int参数errorOffset。
在line 125 (and 8 more lines): new InstanceJavaParser(reader1).parse...()
中
类型InstanceJavaParser中的方法parse()引用缺少的类型ParseException
我可以从哪里下载哪个jar来获得特殊的ParseException?

也许我应该提供更多细节而不适合评论:

为什么我只得到一个虚拟的App.java,而没有涉及JavaParser的内容?
.pom和.jar都放在哪里?
所有.pom和.jar有什么影响?
最佳答案
当您构建JavaParser项目时,将生成该文件。这就是为什么它不在存储库中,这就是为什么我们仍然可以具有零依赖性的原因。
如果问题是您的IDE找不到此文件,请使其指向包含生成的源的目标文件夹中的目录。
