POM error: Failure to find org.springframework.boot - maven

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.

Answer 3

Check Settings.xml file mapping in Eclipse Window->Project->Maven->User Settings, It should be default xml provided from Maven config folder. You might have configured your own xml file which suites for you project needs.

Answer 4

I tried few things
1. set up the settings.xml file
2. Update maven project option for eclipse didin't solved my issue
3. Run the following command manually , my issue got resolved
mvn dependency:purge-local-repository

Answer 5

Change the version of springboot to the next version or previous version and do update the pom file. It worked for me. I had issue with spring boot 2.1.5 so I changed it to 2.1.4 in the pom file and updated it. It worked.

Answer 6

Delete the repository in .m2 folder, perform Maven install and update the project , it worked for me.
Attaching pom.xml file here.

Answer 7

This happened because the STS is not able to find the Parent POM location. You can go to Command Prompt and exectute mvn -x to get location of your Global and Local Settings.xml file.Go to Window-> Preferences-> Maven, and then set the locations for both Gloabal and User level with the above command locations. Then right click on the project and Goto Maven-> UpdateProject. This will solve the problem

I am facing this issue as i am writing this answer. Well seems my office internet settings has restricted downloading content using tools like eclipse. I have faced issues with multiple tools like eclipse, youtube-dl. When I use my mobile internet for my laptop it works fine. That means it has got to do something with the internet settings.
