Could not calculate build plan:
Plugin org.apache.maven.plugins:maven-resources-plugin:2.6 or one of its dependencies
could not be resolved: Failed to read artifact descriptor
for org.apache.maven.plugins:maven-resources-plugin:jar:2.6 Plugin
将maven 本地仓库下的 org.apache.maven.plugins 目录下的所有文件删除，重新下载。
然后update maven project
ok 解决了
