Checkstyle "unable to get class information for @ throws tag 'xxxexception"

In the past two days, run the checkstyle checkCode"Unable to get class information for @ throws tag 'xxxexception" always appears"

 

After reading it for a long time, I couldn't find the reason. The import in the Java class is correct and there is no problem in compiling anything.

The cause is that the class configurationexception, which is mentioned in basic1_builder is not in the run classpath of checkstyle, so checkstyle cannot perform any checks on whether it is a checked exception or a runtime exception or other. so this is not really a warning about your code being bad, but a warning about checkstyle being unable to fully check whether the import and usage of the class configurationexception conforms to the coding styles configured.

 

It turns out that the compiled class is not in the classpath of checkstyle.

Therefore, you only need to configure the compiled class to the <checkstyle/> classpath.

 

In addition, it seems that the line length of checkstyle is also a bit problematic. If it is not more than 120 characters, an error is returned.

In eclipse, I changed the maximum line with in Java> code style> formatter to 100, and then formatted it. Basically, there is no problem.
