The most common targets are: serve - Serves files, on port 3000. lint - Runs gjslint on all sourcefiles to enforce specific syntax. build - Builds singlefile versions of OpenLayers JavaScript and CSS. This is also the default build target which runs when no target is specified. test - Runs the testsuite and displays the results. check - Runs the lint-target, builds some OpenLayers files, and then runs test. Many developers call this target often while working on the code. help - Shows this help. Other less frequently used targets are: apidoc - Builds the API-Documentation using JSDoc3. ci - Builds all examples in various modes and usually takes a long time to finish. This target calls the following targets: lint, build, build-all, test, build-examples, check-examples and apidoc. This is the target run on Travis CI. reallyclean - Remove untracked files from the repository. checkdeps - Checks whether all required development software is installed on your machine. fixme - Will print a list of parts of the code that are marked with either TODO or FIXME. todo - This is an alias for the fixme-target (see above). If no target is given, the build-target will be executed. The above list is not complete, please see the source code for not-mentioned and only seldomly called targets.
