Question

我正在尝试通过以下位置的文章来构建CDAP源代码 -

https://github.com/caskdata/cdap

但是当我尝试使用mvn clean包时，它会给出构建错误 -

Answer 1

kConfigurer.java:69：第一句应以句号结束。

C：\ Users \ admin \ cdap \ cdap-api \ src \ main \ java \ co \ cask \ cdap \ api \ workflow \ WorkflowForkNode.java:21:第一句应以句号结尾。

C：\ Users \ admin \ cdap \ cdap-api \ src \ main \ java \ co \ cask \ cdap \ api \ workflow \ WorkflowSpecification.java:30：第一句应以句号结束。

C：\ Users \ admin \ cdap \ cdap-api \ src \ main \ java \ co \ cask \ cdap \ api \ workflow \ WorkflowToken.java:22:第一句应以句号结束。

我认为在第69行的类kConfigurer.java中，注释中的第一句应以句号结束。

与其他3个陈述类似。

"First sentence should end with a period."

如果你感到困惑。

Checkstyle主要在那里，所以你的代码看起来是统一的，所以要注意它经常这样做。值得庆幸的是，它通常很容易修复。

Answer 2

此错误表示checkstyle存在问题，其中带有注释的第一行不会以突出显示的行上的句点结尾。但是对于这个项目而言，我没有看到任何错误来自开发。

1）你不是从开发分支建设？

2）您是否修改了suppressions.xml文件？ - suppressions.xml第30行已禁用此检查＆lt;抑制检查=＆＃34; JavadocStyle＆＃34;文件=＆＃34; / SRC /（主|积分）/ JAVA /.＆＃34。 /＆gt;。因此，除非您修改了该文件，否则您不应该看到此特定的checkstyle错误。

3）项目中没有名为kConfigurer.java的文件。也许最好在尝试之前删除与CDAP无关的所有文件。

谢谢，
