Likely because projectB has not yet been evaluated.
See:
http://gradle.org/current/docs/userguide/multi_project_builds.html#sub:configuration_time_dependencies
This should work (but I can't say conclusively without seeing the whole build):
evaluationDependsOn ":subfolder1:projectA"
evaluationDependsOn ":subfolder2:projectB"
project(':subfolder1:projectA'){
assemble.dependsOn(':subfolder2:projectB:install')
}
Projects are evaluated top down. So what was happening is that projectB had not
yet been evaluated and therefore did not yet have an install task.
