# opm-core jenkins build scripts: **build.sh**: This script will build dependencies, then build opm-core and execute its tests. It also inspects the $ghbPrBuildComment environmental variable and builds downstreams if requested. It inspects the $ghbPrBuildComment environmental variable to obtain a pull request to use for the modules. It is intended for pre-merge builds of pull requests. To specify a given pull request to use for upstreams and downstreams, trigger line needs to contain <module-name>=<pull request number>. To build with downstreams the trigger line needs to contain 'with downstreams'.
