Recording .buildinfo File
Recording build result into a .buildinfo file is typically done on command line by calling artifact:buildinfo goal after the normal build:
$ mvn clean verify artifact:buildinfo [INFO] Scanning for projects... [INFO] [INFO] ----------------< org.apache.maven.sample:test-project >---------------- [INFO] Building Test Project 1.0-SNAPSHOT [INFO] --------------------------------[ jar ]--------------------------------- ... [INFO] --- maven-artifact-plugin:3.1.0:buildinfo (default-cli) @ test-project --- [INFO] Saved info on build to /tmp/test-project/target/test-project-1.0-SNAPSHOT.buildinfo [INFO] ------------------------------------------------------------------------ [INFO] BUILD SUCCESS [INFO] ------------------------------------------------------------------------
This records data on the current build results into a .buildinfo file using Reproducible Builds .buildinfo for the JVM format.
Notice that if the build is multi-module, only 1 .buildinfo file is generated, in the last module of the reactor, that will record aggregated results for all the modules.
Checking Reproducible Build: Comparing Current Build Against Previous One
When the artifact:buildinfo goal is used with reference.repo command-line parameter, it uses the parameter value as a reference of a remote repository (either its id like central or an url like https://repository.apache.org/content/repositories/maven-1619) to get reference artifacts from it, then compares reference artifacts against current build output to display Reproducible Build output summary:
$ mvn -Papache-release clean verify -Dgpg.skip artifact:buildinfo -Dreference.repo=central [INFO] Scanning for projects... ...
