 可以解决Eclipse 复制其他工程中pom.xml中依赖的jar包后包jar is missing。

 

If hit "Index downloads are disabled, search results may be incomplete." issue.

"Window" --> "Preferences" and choose Maven in the left side.

Now you have to check the box "Download repository index updates on startup"

 

If no "Search Results"

"Window" ---> "Show View" ---> "Maven Repositories" ---> "Global Repositories" 

 

chose "central" click right and "Update Index"
