I found that the plug-in from the eclipse market is still quite useful and installedAfter the m2eclipse-wtp, added support for eclipse web projects, good to use.
The installation sequence should be noted:
InstallM2e, and then installM2eclipse-wtp.
First install the second m2e, and then install the m2eclipse-wtp
Otherwise, errors such as the following are continuously reported:
No plugin found for prefix 'war 'in the current project and in the plugin groups [] available from the repositories [local (C: \ Users \ Administrator \. m2 \ repository), central (http://repo.maven.apache.org/maven2)]
Failure to transfer org. Apache. Maven. plugins: Maven-resources-plugin: pom: 2.5 From http://repo.maven.apache.org/maven2 was cached in the local repository, resolution
Will not be reattempted until the update interval of central has elapsed or updates are forced. original error: cocould not transfer artifact Org. apache. maven. plugins: Maven-resources-plugin: pom: 2.5 from/to central (http://repo.maven.apache.org/maven2): Connection
To http://repo.maven.apache.org refused
After the fix, There will be various errors. At first, I thought the eclipse version was a problem, and then I switched it to a variety of errors.
At last, I adjusted the installation sequence, so I won't report any errors. it's really tough.
