I'm trying to install this: http://asm.ow2.org/eclipse/index.html, but I get this error which makes zero sense to me.
I'm running eclipse Kepler Service Release 1, build id 20130919-0819.
Cannot complete the install because one or more required items could not be found.
Software being installed: Bytecode Outline 2.1.0 (de.loskutov.BytecodeOutline.feature.feature.group 2.1.0)
Missing requirement: Bytecode Outline 2.1.0 (de.loskutov.BytecodeOutline.feature.feature.group 2.1.0) requires 'org.eclipse.help.appserver 0.0.0' but it could not be found
After Eclipse 3.3 "org.eclipse.help.appserver" was removed. See: eclipse:help-appserver
Description: This bundle provided implementation of a Tomcat-based web server application for the Eclipse help system. This was replaced in Eclipse 3.3 with a Jetty-based application server. This bundle defines no API and has been unused in the Eclipse platform for many releases.
It seems that the Eclipse ASM Bytecode Outline plugin was not maintained for quite some time which results in all kind of compatibility problems. For newer versions of Eclipse I therefore recommend installing this alternate version instead.
Use the Eclipse marketplace to find a version for the current eclipse version.
