@Wanderer777, @vazexqi: Participant cs-105 uses Eclipse Class (3.6.1) and AJDT 2.1.2. CodingSpectator 1.0.0.201105300951 has failed to fully install on the Eclipse of this participant.

I downloaded Eclipse SDK 3.6.1 from http://archive.eclipse.org/eclipse/downloads/drops/R-3.6.1-201009090800/index.php and AJDT from http://download.eclipse.org/tools/ajdt/36/update/ajdt_2.1.3_for_eclipse_3.6.zip. I installed AJDT and then CodingSpectator 1.0.0.201105300951 without seeing the problems that the participant has reported.

Update: Participant cs-508 told me on Nov. 1, 2011 that he had managed to install CodingSpectator.

reprogrammer commented 13 years ago

Participant cs-105 kindly let us troubleshoot the installation of CodingSpectator. This participant has installed Eclipse in a "root" space. That is, the owner user and group of all of the installation files of Eclipse are "root". But, the user runs Eclipse with the permissions of a regular user. As a result, all third-party plug-ins that the participant installs on Eclipse go to the home folder of the participant not inside the Eclipse installation folder.

When the participant installed a fresh copy of Eclipse in a "root" space and tried to install CodingSpectator, Eclipse reported the following error message:

Cannot complete the install because of a conflicting dependency.
 Software being installed: CodingSpectator 1.0.0.201107172332 (edu.illinois.codingspectator.feature.group 1.0.0.201107172332)

But, the user successfully installed CodingSpectator on an Eclipse in a "user" space.

I'm using Eclipse 3.7.0 (Build id: I20110613-1736) on Ubuntu 11.04.

It is a known issue that CodingSpectator doesn't install on an instance of Eclipse owned by root.

@Wanderer777:

The plug-in org.eclipse.core.resources [3.7.100.dist] is not specific to Indigo SR1. Both Indigo and Indigo SR1 contain the following plug-in:

@vazexqi, @Wanderer777:

I was able to reproduce this problem and resolve it by running Eclipse as root. Bug 339659 gave me the idea of this workaround.

reprogrammer commented 12 years ago

Participant cs-105 reported the following when he or she installed CodingSpectator by running Eclipse as root:

Unfortunately when I restarted Eclipse as myself (not root), nothing worked, every action led to Eclipse hanging and reporting a Java Heap Space error after a minute or so. So I started Eclipse as root again and uninstalled coding spectator. Now when I start Eclipse as myself, things are back to normal...

It looks like installing CodingSpectator by running as root is not a good solution. This is because when I install CodingSpectator as root, all the created files are created with root permissions. So when I restart Eclipse as myself, those files cannot be edited/changed. In fact, even existing files that are changed during the process are given root permissions. So I just had to go to my workspace and change the owner/group of all the files in .metadata to my user/group because they had been changed to root.
