所以我对Maven还很新，所以我真的不明白整个过程是如何运作的。无论如何我试图让maven编译我的项目，当我运行命令“mvn compile”时，它首先给我一个构建失败，但是如果我运行命令“mvn package”它将成功并且无论如何后续“mvn compile”s之后会工作的。我的问题是我需要将它提交给git，然后将其发送给jenkins进行审核，当时它是失败的，我不知道如何修复它。这是日志

任何帮助都会非常感激。
答案 0 :(得分：1)
在你的POM中，你修改了默认的sourceDirectory（你不应该少用你有充分的理由）
<sourceDirectory>src</sourceDirectory>
因此，maven尝试在编译阶段编译Test类。 JUNIT不可用（JUNIT依赖的范围是测试）。
删除
<sourceDirectory>src</sourceDirectory>
这应该有效
