无法连接到 Maven 进程。 稍后再试。 如果问题仍然存在，请检查 Maven Importing JDK settings 并重新启动 IntelliJ IDEA

Question

I'm trying to add a new dependency in pom.xml in IntelliJ IDEA. After updating the pom.xml file, I right-clicked the file and selected: Maven-> Reload project

Then it shows many errors in the Build->Sync tab:

Cannot connect to the Maven process. Try again later. If the problem persists, check the Maven Importing JDK settings and restart IntelliJ IDEA

Does anyone know how to fix this error? I tried restarting Intellij but didn't help.

maybe is your hosts problem, you can edit the hosts file to

127.0.0.1 localhost

see here .
it works to me.
