[java] Deprecate rules ExcessiveClassLength and ExcessiveMethodLength · Issue #2127 · pmd/pmd · GitHub

Following discussion on #2123, the rules ExcessiveClassLength and ExcessiveMethodLength should be deprecated. Main reasons are (LoC means "lines of code"):

• LoC is noisy, NCSS is a more solid metric (results are code-style independent, comment-insensitive)
• LoC is easily circumvented by bad code style (eg. stuffing several assignments into one, concatenating code lines)
• Enforcing length limits with LoC is not very meaningful, could even be called a bad practice

Rules:

• ExcessiveClassLength
• ExcessiveMethodLength

Instead of these rules, the rule NcssCount could be used.

If needed, the rule "ExcessiveClassLength" can be easily written using the following XPath-expression: //TypeDeclaration[@EndLine - @BeginLine > 1000]. Similarly, for "ExcessiveMethodLength" the XPath expression would be: //MethodDeclaration[@EndLine - @BeginLine > 100].

The plan is, to remove these rules in PMD 7.
