maven构建失败-执行目标org.apache.maven.plugins:maven-checkstyle-plugin失败

Question

我试图通过下面的文章来构建CDAP源代码-

https://github.com/caskdata/cdap

但是当我尝试mvn干净包时，它会产生构建错误-

.
.

Answer 1

kConfigurer.java:69:第一句应该以句号结尾。 C:\Users\admin\cdap\cdap-api\src\main\java\co\cask\cdap\api\workflow\WorkflowForkNode.java:21:第一句应该以句号结尾。 C:\Users\admin\cdap\cdap-api\src\main\java\co\cask\cdap\api\workflow\WorkflowSpecification.java:30:第一句应该以句号结尾。 C:\Users\admin\cdap\cdap-api\src\main\java\co\cask\cdap\api\workflow\WorkflowToken.java:22:第一句应该以句号结尾。

我认为在第69行的kConfigurer.java类中，评论中的第一句应该以句号结尾。

与其他3项声明相似。

检查

"First sentence should end with a period."

或

如果你很困惑的话。

Checkstyle主要是因为您的代码看起来是统一的，所以要注意它会经常这样做。谢天谢地，它通常很容易修复。

Answer 2

此错误表示checkstyle的问题，其中带注释的第一行在突出显示的行上没有以句号结尾。无论具体到这个项目，我没有看到任何错误的发展建设。

( 1)你们不是从开发部门开始建设的吗？

2)您修改了suppressions.xml文件吗？-- suppressions.xml行编号30已禁用此检查< checks="JavadocStyle“files=./src/(主区整合)/java/.”/ >。因此，除非您修改了该文件，否则不应该看到这个特定的校验样式错误。

3)项目中没有名为kConfigurer.java的文件。在尝试之前，最好先删除所有与CDAP无关的文件。

谢谢,
