Update eclipse from galileo to helios on kubuntu

Question

I installed eclipse galileo from kubuntu package manager. For some reason, there is no helios available yet. Then I tried to manually install helios, but when I run it, I get message: "The Eclipse executable launcher was unable to locate its companion shared library."

Then I opened galileo, and installed PDT from helio update site. But due to some galileo - helios incompatability, I get error:

java.lang.NoClassDefFoundError: org/eclipse/wst/css/ui/internal/contentassist/CSSStructuredContentAssistProcessor

when I try to open PHP file.

I read on http://wiki.eclipse.org/FAQ_How_do_I_update_Eclipse%3F that I can update to helios if I add helios update site in Window > Preferences > Install/Update > Available Software Sites, which I tried, but when i run "check for updates" it says that there is nothing to update.

Any idea how to get helios PDT installed on kubuntu?

Answer 1

I would recommend that you download the Eclipse IDE for PHP Developers package from here:

http://www.eclipse.org/downloads/

Make sure that you get one that's correct for your OS and pay particular attention to 32/64 bit variation. You have to match 32/64 bitness of Eclipse with 32/64 bitness of your JVM. Run "java -version" to see the type of JVM that you have. If you don't match these up, Eclipse will not start with a message like the one you are seeing.

Answer 2

For anyone having problems with eclipse Helios on Kubuntu or Ubuntu, I would suggest you remove your current installation and follow the instructions I just posted on my blog after finally getting 3.6.2 working with both the Marketplace Client and Subclipse. I just tried posting the whole entry here but it wouldn't allow the number of hyperlinks required to get the install working.
