There is a problem with STS 3.5.0

https://issuetracker.springsource.com/browse/STS-3792

org.codehaus.groovy.eclipse 2.9.0.xx-201403261719-e43j8 is unknown in the solver!

These are the steps I took to fix it and it allowed me to use eclipse marketplace

  • This seems to have worked perfectly -- much appreciated. I filed a bug against STS 3.5.0 to no avail so far. Thanks. – jwj May 07 '14 at 21:06
  • Still buggy with STS 3.5.1, I hope this will go away on the next release. – Titi Wangsa bin Damhore May 08 '14 at 08:37

    Yeah, I forgot to mention that too: I upgraded to 3.5.1 yesterday and saw that it was still having an issue, so decided to search and see if anyone had come up with a real workaround/solution and found this. Hopefully they get it all sorted out. Apparently it was kind of a workaround they had to do to get Java 8 support working with the update sites. – jwj May 08 '14 at 16:21
  • This issue was still happening for me with 3.6.0 and this answer solved the problem. – Night Owl Mar 21 '15 at 01:28

I had the same problem. Check if groovy-eclipse is installed. If it is not, then you need to install it first then install STS.
