Maven and manifest

Question

一切正常，但在我向Eclipse动态Web项目添加了一个类之后，Maven开始:

目标 m2e-wtp web资源 meta - inf MANIFEST。MF(文件未找到)

我不再做了-如何治愈它-告诉我PLZ。当然，我清理了Maven项目并重新安装，但没有任何变化。这是我的诗

Answer 1

进入项目的根目录。无论文件在哪里，试着做一个

mvn eclipse:clean 

然后

mvn eclipse:eclipse

更多信息，您可以通过本教程:m2e-wtp错误:/target/m2e-wtp/web-resources/META-INF/MANIFEST。MF(无此文件或目录)

Answer 2

我认为这是一个Eclipse bug。在使用命令clean install运行 Maven构建之前。现在我只运行Maven Clean，然后运行Maven install，问题就解决了。
