Hello,

since Kepler I looked into Eclipse E4 development. Updating to Oxygen now I can't export my product. Within Eclipse itself everything is fine. It doesn't matter, if I'm using:
- three project: product, plugin and feature
- two projects: product and plugin
- or just one combining product and plugin

Whatever I do, as soon as I try to use the "Eclipse Product export wizard" the wizards fails on the Apache Batik CSS:
"Missing requirement: Eclipse CSS Core Support 0.12.101.v20170712-1547 (org.eclipse.e4.ui.css.core 0.12.101.v20170712-1547) requires 'bundle org.apache.batik.css 1.7.0' but it could not be found"

Actually I can imagine four theoretical solutions:
1 - Force the wizard to do the same as Eclipse itself and simply export the product as I request
2 - Upgrade org.eclipse.e4.ui.css.core to use Apache Batik CSS 1.8.0
3 - Downgrade org.eclipse.e4.ui.css.core to use Apache Batik CSS 1.6.0
4 - Install Apache Batik CSS 1.7.0

I already tried installing Apache Batik CSS 1.7.0 using the Oxygen Orbit update site, but the org.apache.batik.css within my product ("Content" tab "Plug-ins and Fragments") still references version 1.8.0.v20170214-1941 and I can't change it.
Searching the web for help I found many old post but no solution I could apply.
What do I need to do/change to get my E4 running outside Eclipse as well?

Many thanks in advance

The next version apperas to have bypassed 1.8 and gone straight to 1.9. http://git.eclipse.org/c/platform/eclipse.platform.ui.git/commit/bundles/org.eclipse.e4.ui.css.core/META-INF/MANIFEST.MF?id=634df2364cbc1ba9ef45a33e4968f517e47682de . Why can't you change it as you move from Kepler to Oxygen?

Thanks for the answer, but where do I get that updated org.eclipse.e4.ui.css.core from? My feature project tells me I'm using version 0.12.101.v20170712-1547. Looking into my Target Platform there is no other version available. My understanding was that sticking to the Update Sites everything should be fine and I don't need to care about versions and manual JAR integration from different sources. As looking for updates is the first thing I do after launching Eclipse, I should already have the latest version.

These are the Update Site I'm using:
E4 Spies: http://download.eclipse.org/e4/snapshots/org.eclipse.e4.tools/latest/
Eclipse E4:
http://download.eclipse.org/e4/updates/0.16/
http://download.eclipse.org/e4/updates/0.17/
Eclipse Packaging Project: http://download.eclipse.org/technology/epp/packages/oxygen
M2Eclipse: http://download.eclipse.org/technology/m2e/releases
Oomph Latest Milestone: http://download.eclipse.org/oomph/updates/milestone/latest
Orbit Build Repository: http://download.eclipse.org/tools/orbit/downloads/drops/R20170919201930/repository
Oxygen: http://download.eclipse.org/releases/oxygen
The Eclipse Project Updates: http://download.eclipse.org/eclipse/updates/4.7

Meanwhile I found a quick and dirty workaround in order to resolve the Batik 1.7.0 JAR references:
- I downloaded all required libraries, stored them in a separate folder on my harddrive
- added this folder to my Target Platform
- deactivated Batik 1.6.0 and 1.8.0 versions in the Target Platform
So 1.7.0 was finally sucessfully resolved. But this trick can impossibly be the recommended solution.

My first glance into Eclipse was Juno. Ever since a tried each version, but never found the time for a deep dive especially as exceeding tutorials I always ended up with issues, this time the Batik one. But now I'm working on a project I'd like to implement with: E4 technology.

Do you have an update on this issue? Because I ran into the same problem updating my target platform to Eclipse Oxygen. I get this error even if I validate the plugins in my Eclipse Launch Configuration in the following way: Run -> Run Configurations -> Select my product launch configuration -> Tab "Plug-ins" -> Button "Validate Plug-ins"

I'm on Oxegen as well now. I reinstalled, updated and retried everything until it finally worked. Moving forward and backwards through my backups, I still neither know how I finally managed and least of all, how it is supposed to work straight away. Any step-by-step tutorial with proven working result and named libraries with precisely defined version numbers is highly appreciated.

Had same problem on RCP export. Could run within Eclipse IDE, but not the export.

Solution:
Somehow my Oxygen install directory had old 1.6.0 versions of the org.apache.batik.css and, I think, the org.apache.batik.util.gui. plugins. The actual version with Oxygen is 1.8.0. You need to delete all of the old ones, leaving the 1.8.0s, and rebuild. At least for me, I avoided an epic on today's tool delivery.
