[英]How to discover repeating code lines with PMD
问题描述
A popular attempt to bypass Salesforce Apex code coverage rules are code busters where one statement is used in thousands of repeating lines.
绕过 Salesforce Apex 代码覆盖规则的一种流行尝试是代码破坏者，其中一个语句在数千个重复行中使用。
We have found variations like i=1;我们发现了像i=1;这样的变化i=1; or a++;或a++; or a=b;或a=b; with endless variations for the variable name.变量名的变化无穷无尽。 All have in common that two (or more) consecutive lines (excluding empty or comments) are identical.所有的共同点是两个（或更多）连续行（不包括空行或注释）是相同的。

This sound more like a use case for the copy paste detector.这听起来更像是复制粘贴检测器的用例。 This is a separate tool also available from PMD: https://pmd.github.io/pmd-6.12.0/pmd_userdocs_cpd.html这是一个单独的工具，也可以从 PMD 获得： https : //pmd.github.io/pmd-6.12.0/pmd_userdocs_cpd.html
However, CPD is focused on finding duplicated code between different files, whereas you seem to be looking for duplicated code within one file.但是，CPD 专注于查找不同文件之间的重复代码，而您似乎正在寻找一个文件中的重复代码。
