Code coverage and generated code

Jacoco

When analysing code coverage jacoco analyses compiles classes. If you have generated code, jacoco will take it for analysis, unless your classes are annotated with an annotation havin 'Generated' in its name.

The filter used by jacoco to filter out all classes annotated with ..Generated is AnnotationGeneratedFilter

Docker executor

The Docker executor when used with GitLab CI, connects to Docker Engine and runs each build in a separate and isolated container. The image for the job is :

• either the predefined image set up in the runner configuration (config.toml)
• or the image set up in .gitlab-ci.yml

Using docker commands in jobs

Using docker on CICD jobs in GitLab means using Docker-in-Docker (dind):

Lines endings

Windows - CRLF - carriage retur + linefeed - \r\n Linux - LF - linefeed - \n MAC - CR - carriage return - \r

Global configuration on working machine

core.autocrlf configuration setting:

• true - this converts LF endings into CRLF when you check out code, converts CRLF line endings into LF when you add a file to the index; usually used on windows machines
• input - this converts CRLF to LF on commit only; used on Linux machines; if a file with CRLF endings accidentally gets introduced, it gets fixed on commit
