Eclipse Photon - Eclipse Marketplace not launching

Question

I just installed Eclipse Photon. I migraded one project from Oxygen to it - everything is working fine.

The problem I noticed is that I cannot open the Eclipse Marke

Answer 1

I managed to find the problem and fix it. I went to: Help -> About Eclipse IDE -> clicked on "Installation Details" -> tab "Configuration" -> Clicked on "View Error Log"

The default browser opened and there I noticed the following stack trace:

!ENTRY org.eclipse.ui 4 0 2018-06-28 10:38:21.036
!MESSAGE Unhandled event loop exception
!STACK 0
org.eclipse.e4.core.di.InjectionException: java.lang.IllegalArgumentException: Illegal character in path at index 16: file:/C:/Eclipse Photon/eclipse/configuration/
    at org.eclipse.e4.core.internal.di.MethodRequestor.execute(MethodRequestor.java:65)

It was the space character in the folder named by me: "Eclipse Photon". I renamed it to "EclipsePhoton" and the marketplace opened successfully.

Short answer: Make sure you do not have any spaces in the Eclipse installation file path.

I fixed the issue with the solution from this link: https://www.chrisguindon.com/post/marketplace-client-not-opening-in-photon/

Steps:

1. Go to Help > Install New Software
2. Paste the Marketplace Client update site url into the “Work with” field: http://download.eclipse.org/mpc/photon
3. Select the “EPP Marketplace Client” checkbox
4. Follow the wizard and restart your Eclipse to finish the installation.

I had this problem on my Ubuntu 18.04 machine, none of the above helped.

After hours of searching, I found a working solution: enable theming under Window - Preferences - General - Appearance

I had this disabled, so Eclipse uses my GTK Theme (Arc dark) and looks better. But enabling it makes Marketplace start again.

The stacktrace in the Eclipse error log (Window - Show View - Error Log) contained a hint that lead me to the theming option.

Addition to actunderdc answer:

He is right. There is a bug if there is a space in the installation path. If you want to install in the Program Files folder, you can use the windows shortnames.

Find the shortname of the folder in cmd by using dir /X. For C:\Program Files it is something like PROGRAM~1.

When you got the shortname, you can add the folowing at the top of your eclipse.ini File in the same directory of the eclipse.exe

-launcher C:\PROGRAM~1\eclipse\jee\photon

Make sure to adjust it to your installation path. After you have done this, marketplace can be opened. But when I open Help -> About -> Instalation Details -> Configuration it shows me two -launcher parameters with the long and the short name. I don't know, if it could cause sideeffects.

I opened a Bugreport at bugs.eclipse.org.

Had similar problem, this is what I did:

NOTE: If you have any other firewall software then make sure to allow eclipse though it & also check if your computer's time is proper(else leave this).

Open Eclipse > Help > Install New Software.. >
Enter link in work with " http://download.eclipse.org/mpc/photon/ " > (after lodaing) select the EPP Marketplace Client and install it

• I had error while installing it, I just allowed eclipse through firewall then marketplace client updated smoothly. Then I restarted eclipse and marketplace opened.

Hope this helps.

First when trying to use WindowBuilder (SWT) in Eclipse JEE 4.8 you must remove all spaces from your Eclipse folder name that contains all its files. This first step was discovered via link:

Eclipse Photon - Eclipse Marketplace not launching

Secondly, is this link tells the second half of the mystery. If you go to:

http://download.eclipse.org/windowbuilder/WB/integration/4.8/

you will see on the left hand side "show directory contents" which will have "repository.zip" file as last file of this expanded list. Download this (~39Mb). Note path to this file, then in eclipse click on "help" (last menu item), then click on "Install New Software...", then click "add", then click "archive" and go to path of saved "repository.zip" and select it. You will see square check box now indicates file to install.

I believe one must then click "continue" (check box already checked for WindowBuilder install item), then confirm when all files to be installed show are shown on screen, then finally click "finish". After the file is loaded in archive step I am not sure of the exact verbiage used for remaining steps but I believe what I have said is mostly accurate and after adding archive it will be self evident (piece of cake) what steps to follow. Finally to check if Window builder is installed go to (in top menu items) "file" then "new" then "other" and then finally scroll down list and WindowBuilder should be in this list, otherwise you landed a goose egg and something went wrong.
