Binary distribution is built under agent/dist/target.
Building requires Java 7+ (in order to perform Immutables annotation processing) and Maven 3.1.0+.
Glowroot uses Immutables annotation processing to eliminate maintenance on lots of boilerplate code. If you are using Eclipse, this requires installing the m2e-apt plugin and changing Window > Preferences > Maven > Annotation Processing to "Automatically configure JDT APT".
To work on the UI, run org.glowroot.ui.sandbox.UiSandboxMain under a debugger inside your favorite IDE. This starts Glowroot and generates a variety of sample traces to give the UI something to display. Connect your browser to http://localhost:4000.
mvn clean install, Node, Bower and Grunt are installed locally under the
ui directory (thanks to the frontend-maven-plugin).
If you are modifying web assets, you either need to run grunt to re-build them after each change, or (better) run
grunt serve from the
ui directory and connect your browser to http://localhost:9000.
grunt serve serves up the Glowroot web assets to the browser without the concat/minify/rev step, which makes testing/debugging much easier. It reverse proxies non- static resource requests to http://localhost:4000 to be handled by Glowroot. It also watches for changes to the files and performs live-reload of web assets inside the browser.
Integration tests are run during Maven's standard
integration-test lifecycle phase.
The Glowroot agent has an integration test harness which makes it easy to run sample application code and then validate the data captured by the agent. The integration test harness is able to run tests both using a custom weaving class loader (which is very convenient for running and debugging inside your favorite IDE), and by spawning a JVM with the -javaagent flag (which more correctly simulates real world conditions).
Browser-based integration tests are run using WebDriver. By default they run against Firefox. Thanks to Sauce Labs, they also run against Chrome, IE (9, 10, 11) and Safari (6, 7, 8, 9) during every Travis CI build (see the jobs with TARGET=saucelabs).
