刚刚装的ECLIPSE，配置了阿里云的MAVEN，没有maven dependencies，也没有 enable maven dependency

Posted 2023-05-15

CLASSPATH里面有<classpathentry kind="con"path="org.eclipse.m2e.MAVEN2_CLASSPATH_CONTAINER"> <attributes> <attribute name="maven.pomderived" value="true"/> </attributes> </classpathentry>求问，还能怎么办，试着装了MARS版本也没办法updata project 里面 updata dependency 是灰色的pom.xml如图，就算我添加了dependencies也无效。

参考技术A 这个和你配置了哪个的nexus没关系吧，仓库地址不正确大不了就是拉取不到文件，你是用的eclipse自带的maven插件还是自己下载的maven？如果是eclipse自带，就去自己下个maven，然后在eclipse里面配置使用你自己安装的maven，再一个就是，你这个工程是maven工程吗？

基于阿里云的maven配置settings.xml
