Tried to install Architexa after a fairly vanilla install of Neon (Java edition).Got the following issue as others reported:

An error occurred while installing the items
session context was:(, phase=org.eclipse.equinox.internal.p2.engine.phases.Install, operand=null --> [R], action=).
Failed to prepare partial IU: [R]

Installed "Eclipse 2.0 Style Plugin Support" as per FriendOf Eclipse. Did not seem to make a difference.

Installed "UML Lab" plug-in (did not get license or enable trial).
Tried Architexa again, and surprisingly got further along with the install, but got the following error:

Cannot complete the install because one or more required items could not be found.
Software currently installed: Architexa RSE (Rich Source Explorer) - (Required) (
Missing requirement: Integration Plug-in (CVS, etc) (com.architexa.diagrams.generate requires 'bundle 0.0.0' but it could not be found
Cannot satisfy dependency:
From: Architexa RSE (Rich Source Explorer) - (Required) (
To: com.architexa.diagrams.generate []

Installed CVS Integration plug-in.

Tried to install Architexa again and it worked.

I would probably be useful if Architexa developers would try to install it on top of an Eclipse install from scratch. They may be assuming certain plug-ins installed by default that are no longer there.

As with the other reviewers, initial installation required the "2.0 plugin support" plugin. However, once installed, the sequence diagrams will not work at all due to :
java.lang.NoSuchMethodException: org.eclipse.jdt.internal.ui.javaeditor.ASTProvider.getAST(org.eclipse.jdt.core.IJavaElement, org.eclipse.jdt.ui.SharedASTProvider$WAIT_FLAG, org.eclipse.core.runtime.IProgressMonitor)

Hi FriendOfEclipse,

Thanks! You saved my day.
Worked in my case.

Hi sinedanat,
I found this solution in the thread about an error in Veloeclipse which seems to be similar:

- Go to: Help -> Install New Software...
- Choose: Eclipse Project Updates -
- Install: "Eclipse 2.0 Style Plugin Support" from "Eclipse Tests, Examples, and Extras"
- Now install Architexa

Works for me

Hi FriendOfEclipse,
Works in Eclipse 4.5 Mars too.

It's impossible to install architexa plugin in Eclipse 4.4 Luna due to error:
"session context was:(profile=DefaultProfile, phase=org.eclipse.equinox.internal.p2.engine.phases.Install, operand=null --> [R], action=).
Failed to prepare partial IU: [R]"

Also shows the same error with 4.6 Neon.
