转stackoverflow上的一个解决方法：
I ran into a similar issue today and found that this question also has recently been asked and answered at the atlassian forum as well. My solution was to install slf4j based on guidelines from this blog post about "SLF4J Logging in Eclipse Plugins".
To extract, here is what I did:
Eclipse -> Help -> Install New Software
Add a new software site:
Name: slf4j
Url: http://www.fuin.org/p2-repository/
Expand "Maven osgi-bundles" and select "slf4j-api"
Click "Next" and follow the installation.
After the installation has completed (and Eclipse has been restarted) I was then able to install the maven plugin.
