Could be a problem w/ our Akamai mirroring of http://download.jboss.org/jbosstools/static/targetplatforms/jbosstoolstarget/4.51.0.Final/REPO/ which is the target platform URL for the JBoss Tools installation.
Workaround is to download this archived update site (zip) and add that to Eclipse (Help > Install ...) so that the missing IU can be resolved:
If this is in fact an Akamai problem, can you assist in debugging it by telling me where you are on the planet and if possible, what your externally-facing IP address is?
Hi , i from Hong Kong and i already downloaded the jboss tools zip file to manual install , but still pop that error
You need to download the TARGET PLATFORM zip to resolve this missing dependency. It's not in the JBoss Tools Update Site Zip.
