无法通过以下Maven错误org.codehaus.mojo：license-maven-plugin：1.12：check-file-header构建Maven项目

Question

我试图在Windows平台上使用带有m2e的eclipse构建Kylo v_0.9.1。 但是项目构建在kylo-operational-metadata-jpa失败，并引发以下错误。

Answer 1

License Maven插件检测到一些没有头的文件，因此引发错误。 您可以通过运行以下命令来解决此问题：

$ mvn license:update-file-header

这应该将标头添加到丢失的文件中。 然后，您可以再次尝试构建。

Answer 2

Maven输出表明您正在尝试构建Kylo 0.9.2-SNAPSHOT，这是一个不稳定的版本，Kylo团队不支持。

要构建Kylo 0.9.1，请尝试以下命令：

git checkout v0.9.1.1
mvn clean install -DskipTests
