java - 无法构建 Maven 项目，并出现以下 Maven 错误 org.codehaus.mojo :license-maven-plugin:1. 12:check-file-header

Question

我正在尝试在Windows平台上使用eclipse和m2e构建Kylo v_0.9.1。但项目构建在 kylo-operational-metadata-jpa 处失败并抛出以下错误。

Answer 1

License Maven Plugin正在检测一些没有 header 的文件，因此引发错误。您可以通过运行以下命令来修复此问题:

$ mvn license:update-file-header

这应该将 header 添加到丢失的文件中。然后您可以再次尝试构建。
