| <p>This will run static analysis, unit tests, compile classes, and package the projects into JARs. It will <em>not</em> generate the source or binary distribution tarball. Note that this build may take some time to complete.</p> |
| <p>In addition to the basic stages, you may also want to add the following profiles and properties:</p> |
| <ul> |
| <li><strong>-Pdist</strong> - Distribution profile: Generates the binary distribution tarball by pulling in core extensions and dependencies and packaging the files as <code>distribution/target/apache-druid-x.x.x-bin.tar.gz</code></li> |
| <li><strong>-Papache-release</strong> - Apache release profile: Generates GPG signature and checksums, and builds the source distribution tarball as <code>distribution/target/apache-druid-x.x.x-src.tar.gz</code></li> |
| <li><strong>-Prat</strong> - Apache Rat profile: Runs the Apache Rat license audit tool</li> |
| <li><strong>-DskipTests</strong> - Skips unit tests (which reduces build time)</li> |
| <li><strong>-Dweb.console.skip=true</strong> - Skip front end project</li> |
| </ul> |
| <p>Putting these together, if you wish to build the source and binary distributions with signatures and checksums, audit licenses, and skip the unit tests, you would run:</p> |
