maven - In what lifecycle point are tests ignored when building? -

i trying understand maven build lifecycle when regarding tests: let's have project class in src/main folder , 1 in src/test. when run mvn install, get's compiled, tested, packaged , installed.

until thought maven not package tests in snapshot, because not "production" code. true? in case, when maven ignores test files?

what said maven lifecycle true. "main" phases include:

• compile: in phase, maven-compiler-plugin:compile goal run compiles main code of project.
• test-compile: in phase, maven-compiler-plugin:testcompile goal run compiles test code of project.
• test: in phase, maven-surefire-plugin:test goal run , unit tests executed.
• package: in phase, maven-jar-plugin:jar goal run , creates jar of current project. default, jar include classes under target/classes, contains main classes, not test classes located inside target/test-classes. @ step maven ignores test classes.
• install: in phase, maven-install-plugin:install install main artifact, , every attached artifact, local repository.

to answer more precisely, it's not maven ignores test classes, default, packaging process considers main classes. can configure package test classes maven-jar-plugin:test-jar goal inside attached artifact.
