由 Maven 构建

用法

记录.buildinfo文件

将构建结果记录到.buildinfo文件中通常是通过在正常构建后调用artifact:buildinfo目标在命令行上完成的：

$ 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:3.2.0: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] ------------------------------------------------------------------------

这会将当前构建结果的数据记录到一个.buildinfo文件中，该文件使用Reproducible Builds .buildinfo为 JVM格式。

请注意，如果构建是多模块的，则仅在反应器的最后一个模块中生成 1 个.buildinfo文件，该文件将记录所有模块的聚合结果。

检查可重现的构建：将当前构建与以前的构建进行比较

artifact:compare目标将参考工件与当前构建输出进行比较以显示Reproducible Build 输出摘要：

$ mvn -Papache-release clean verify -Dgpg.skip artifact:compare
