end

#var(libs, var_name, var_value) ⇒ Object

Write a classpathentry of kind ‘var’ (variable) for a library in a local repo.

  • libs is an array of library paths.

  • var_name is a variable name as defined in Eclipse (e.g., ‘M2_REPO’).

  • var_value is the value of this variable (e.g., ‘/home/me/.m2’).

E.g., var([lib1, lib2], 'M2_REPO', '/home/me/.m2/repo')
