Question

我正在尝试从mac上的命令行启动Lint4J（0.9.1）。我想在一个小型测试课上运行它。但不幸的是我总是得到一个空指针异常。我有JDK 1.8.0

我的测试班：

package ch.ntb.sir.testmain;
public class TestMain {}

我从官方网站下载了lint4j软件包。它与测试类不在同一个文件夹中。

这是我执行的命令：

/Users/.../lib/lint4j-0.9.1/bin/lint4j -sourcepath /Users/.../ClassToCheck/src ch.ntb.sir.testmain

我从我的测试类的项目文件夹中的终端执行它。

我得到的是输出：

我发现在这些网站上没有任何帮助我：

并且在lint4j.pdf中也没什么用处

欢迎所有提示！谢谢你的帮助。

我已经了解到，Lint4J已经死了＃34;项目。上次更新于2007年

Static Analysis tool recommendation for Java?

https://github.com/checkstyle/checkstyle/wiki/Java-static-code-analysis-tools

因此将它用于新项目是一个坏主意。

我会尝试：FindBugs，Checkstyle，PMD ......他们的最后一次更新发生在2015-2016之间

命令行中的Lint4J给出了NullPointerException
