问题:
I created a Java Gradle project in IntelliJ IDEA 15.0.3. But I am getting the following error.
Unindexed remote maven repositories found. Disable... The following repositories used in your gradle projects were not indexed yet: http://repo1.maven.org/maven2 If you want to use dependency completion for these repositories artifacts, Open Repositories List, select required repositories and press "Update" button (show balloon)
When I open the repositories list and click update, I am getting the following error
java.lang.RuntimeException: java.io.IOException: Transfer for nexus-maven-repository-index.properties failed
回答1:
In your build.gradle repositories section replace mavencentral() with another mirror, like so:
repositories { maven { url "http://uk.maven.org/maven2" } }
then when you get the "Unindexed remote maven repositories found" go to the repositories view and press update. that should do it

A possible (though not the only cause for this issue is, that you are behind a firewall that is blocking your connection). In this case you may need to configure a proxy server for Maven.
In my case it helped to just create a new file named settings.xml with the following contents and place it under C:\Users\<username>\.m2\ (or ~/.m2 on linux):
<settings> <proxies> <proxy> <id>HTTP proxy</id> <active>true</active> <protocol>http</protocol> <host>REPLACE_BY_IP_OR_HOSTNAME</host> <port>REPLACE_BY_PORT_NUMBER</port> </proxy> <proxy> <id>HTTPS proxy</id> <active>true</active> <protocol>https</protocol> <host>REPLACE_BY_IP_OR_HOSTNAME</host> <port>REPLACE_BY_PORT_NUMBER</port> </proxy> </proxies> </settings>
Replace host and port for your specific environment.

Adding proxy settings to VM options worked. This answer helped me to set the proxy settings on IntelliJ for Maven
