Eclipse (STS) Welcome dash board error - Unable to see welcome dash board

Question

when I am trying start STS (Spring Tool Suite) I am getting this error:

Plug-in "org.springsource.ide.eclipse.commons.gettingstarted" was unable to instantiate class "org.springsource.ide.eclipse.commons.gettingstarted.dashboard.WelcomeDashboard".

This is my .log file in the workspace .metadata directory:

!MESSAGE Warning: EGit couldn't detect the installation path "gitPrefix" of native Git. Hence EGit can't respect system level
Git settings which might be configured in ${gitPrefix}/etc/gitconfig under the native Git installation directory.
The most important of these settings is core.autocrlf. Git for Windows by default sets this parameter to true in
this system level configuration. The Git installation location can be configured on the
Team > Git > Configuration preference page's 'System Settings' tab.
This warning can be switched off on the Team > Git > Confirmations and Warnings preference page.

!MESSAGE Warning: The environment variable HOME is not set. The following directory will be used to store the Git
user global configuration and to define the default location to store repositories: 'C:\Users\Geek Labs'. If this is
not correct please set the HOME environment variable and restart Eclipse. Otherwise Git for Windows and
EGit might behave differently since they see different configuration options.

I resolved this by Extracting to simple folder named STS Folder . and then run STS.exe with proper location ( like not run from usb and anyother source ) . In short C/D or any Drive with small folder name .

Answer 3

Go to your eclipse or spring tool suit, check what kind of eclipse..

go to ->> http://dist.springsource.com/snapshot/STS/nightly-distributions.html

find a relevant one for your tool (eg: if yours is eclipse oxygen means copy Oxygen link (http://dist.springsource.com/snapshot/TOOLS/nightly/e4.7) ).

then goto your tool -> help -> install new software, add the link, just name it anything. ok it will show the available software updates for you.

select all and install it... it will ask to restart .. just restart. issue will be fixed.

Answer 4

I'm not sure if this is going to help, but this error happened to me on Windows 10. What I did to get rid off the error was to uncompress the zip using 7-zip.

7-zip

Answer 5

Luna (4.4.2) install:

I was unable to get any of the answers mentioned above to work, but the comment above that mentioned the link (spring.io/tools/sts/all) by jplandrain set me on the right path.

- Note:

The first time I attempted all of the below steps, I was still having issues. My final result was a success after reinstalling a fresh install of Luna and repeating the below steps (less the uninstall of previously installed spring software)

1. uninstall all previous spring related software (unless this is your first attempt)
2. restart eclipse
3. double check everything uninstalled
4. restart computer
5. go to link (spring.io/tools/sts/all) and copy the below link from under the "Update Sites" section.
   • At the time of this writing (for Luna), it was: "http://dist.springsource.com/release/TOOLS/update/e4.4/"
6. (Mac) Help -> Install New Software… -> Add…
7. Fill out the name and location sections
   • Name: "Spring Tool Suite"
   • Location: "http://dist.springsource.com/release/TOOLS/update/e4.4/"
   • 
8. Select All -> Next
   • 
9. Wait...
   10. Choose “Update my installation to be compatible with the items being installed” -> Next -> Next
       • 
   11. Choose “Accept the terms of the license agreements” (if you want to proceed) -> Finish
   12. Restart eclipse
   13. Success! (If not, you may want to try doing a fresh install of eclipse)
       • Observe Spring Tool Suite dashboard once it restarts

Answer 6

If you use Eclipse Mars 4.5 just go to eclipse config, then "Spring" -> "Dashboard" then "Use old Dashboard" - switch on. then "Apply"

it works!

Answer 7

I was looking for the answer for hours. Finally the solution: Install Oracle JDK instead of Open JDK and the problem is gone.

Answer 9

I also had the same problem. I have STS with following configuration (Help->About Spring Tool Suite) :

Version: 3.6.3.RELEASE
Build Id: 201411281415
Platform: Eclipse Luna SR1 (4.4.1)

Here is what I did -

1. Go to Help-> Install New Software
2. Added http://dist.springsource.com/snapshot/TOOLS/nightly/e4.4 in the textfield "Work with". Click "Add" button. Provide relevant name and press ok button. Note: I chose mentioned link from STS Nightly Builds. Many links for different versions are shown. Choose the link according to your Platform version(mine is Platform: Eclipse Luna SR1 (4.4.1) as shown above).
3. Then list is populated(see picture).

4. I selected all the elements in the list and installed all.

For me it worked and hopefully will work for you as well.

Answer 10

It is not really fixed with 3.6.3, because I have now the same issue after upgrading to 3.6.3-Release.

EDIT: But for my solution, after installing I went to "install new software", then I choose link of SpringSource Luna Eclipse Update Site, and then I saw, Dashboard was not installed, and installed it then.

EDIT 2: I am not able to install, cos eclipse says, there is already a newer version installed. I really must say, the last versions of STS from 3.5.x, there were often problems when updating sts. And always similar problems, that at least I removed STS and installed a new version then from the cratch ... :-(

Answer 11

This issue is solved in spring-tool-suite-3.6.3.RELEASE

https://issuetracker.springsource.com/browse/STS-3733

"You are running STS on top of Eclipse Luna? It looks like you used an update site that was created for Eclipse 4.3 or previous versions. The JavaFX components are those for Eclipse 4.3 (and earlier), but not the ones for Eclipse 4.4 (Luna). What update site did you use? The fix for this would be to re-install the STS components into Eclipse Luna from the 4.4-based update site (mentioned on top of that page) or download a ready-to-use nightly build of STS 3.6.0 based on Eclipse Luna from here: http://dist.springsource.com/snapshot/STS/nightly-distributions.html"
