POM error: Failure to find org.springframework.boot

Question

I have been trying to setup a spring boot project but am getting an error. I researched and tried various options but no luck so far. Any help would be appreciated.

Project build error: Non-resolvable parent POM: Failure to find org.springframework.boot:spring-boot-starter-parent:pom:1.1.3.RELEASE in 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 and 'parent.relativePath' points at no local POM

POM.XML (error in parent tag)

Answer 1

There might have been some intermittent Internet issue or something. I was facing the same problem yesterday. Updating the the project (On STS or Eclipse, right click on the project and Maven -> Update project -> tick everything except Offline) after sometime fixed it.

Answer 2

I got a similar exception while maven-build process.

If you are using a proxy network - update settings.xml in your maven folder

../apache-maven-3.2.3\conf/settings.xml 

settings.xml content

<proxies>     <proxy>       <id>...</id>       <active>true</active>       <protocol>http</protocol>       <username>....</username>       <password>....</password>       <host>....</host>       <port>....</port>       <nonProxyHosts>local.net|some.host.com</nonProxyHosts>     </proxy>    </proxies>  project(right click) -> Maven -> Update project -> tick everything (except OfflinI) 

I got the issue resolved.
