生成maven项目失败，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来构建Kylo v_0.9.1。但项目构建在kylo-operational-metadata-jpa失败，并抛出以下错误。

Answer 1

License Maven Plugin正在检测一些没有标头的文件，因此抛出错误。您可以通过运行以下命令来修复此问题：

$ mvn license:update-file-header

这应该会将头文件添加到丢失的文件中。然后，您可以再次尝试构建。

Answer 2

Maven的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，并且不受Kylo团队的支持。

要构建Kylo 0.9.1，请尝试以下命令：

git checkout v0.9.1.1
mvn clean install -DskipTests
