Build
SpotBugs is built using Gradle. The recommended way to obtain it is to simply run the gradlew (or gradlew.bat) wrapper, which will automatically download and run the correct version as needed (using the settings in gradle/wrapper/gradle-wrapper.properties).
Building SpotBugs requires JDK 21 to run all the tests (using SpotBugs requires JDK 11 or above, but it can analyze code compiled with older versions).
To see a list of build options, run gradle tasks (or gradlew tasks). The build task will perform a full build and test.
To build the SpotBugs plugin for Eclipse, you'll need to create the file eclipsePlugin/local.properties, containing a property eclipseRoot.dir that points to an Eclipse installation's root directory (see .github/workflows/release.yml for an example), then run the build.
To prepare Eclipse environment only, run ./gradlew eclipse. See also detailed steps.
