Get lines of code in src folder skipping comments and empty lines

Question

Hi I already have something to get the lines of code but still it out puts the count having empty lines and comments counted.

git ls-files | grep "\.java$" | xargs wc -l

Can you modify this to skip comments and blank lines..?

Thanks in advance

Try CLOC, it can lists numbers in great detail. You need to install CLOC first using syntax brew install cloc

cloc $(git ls-files)

Sample output for reference:

20 text files.
      20 unique files.                              
       6 files ignored.

Most test coverage tools also calculate LOC. For instance, Jacoco spits this out to Jenkins.
