Error installing juno eclipse

Question

Last week I downloaded the new version of Eclipse, juno version. I just tried to install Glassfish 3.1 and got the following error:

An error occurred while collecting items to be installed
session context was: (profile = epp.package.jee, org.eclipse.equinox.internal.p2.engine.phases.Collect phase =, operand =, action =).

What does this error mean? How do I fix it?

Answer 1

取消选中“在安装过程中联系所有更新站点以找到所需的软件”复选框，解决了安装/升级问题。

Answer 2

I have found a workaround: try installing glassfish+glassfish tools manually (Help -> Install New Software...), update site is http://download.java.net/glassfish/eclipse/juno .

This installs the whole app server but you can delete it later and add your own.

Answer 3

It looks like this may be a bug ( reported ) with glassfish itself. Perhaps by now (a year later) it has been addressed. You might check in and see if the glassfish plugin has been fixed. Best wishes!
