You said you're using the Neon-Repository with Eclipse Oxygen. Try the Repository for Oxygen and see if that works:

How to install the new JetBrains code editor Fleet?

I just seen that Fleet, the new JetBrains code editor is available on JetBrains Toolbox. But in mine, I am not able to see it. I tried to search for update, maybe I'll see it in the list but nothing happens.
So I want to know if someone is able to see in JetBrains Toolbox or already install it. If so, please help me to install also. I am using Ubuntu 18.04 LTS.
It's not available yet. You can subscribe to be notified when the open preview is available.
JetBrains Fleet is now in EAP (Early Access Preview). You can install it through JetBrains Toolbox.

Cannot Find the TensorFlow Developer Certificate Plugin in the PyCharm Plugin Marketplace

I paid to take the TensorFlow Developer Certificate exam, and I'm now supposed to install the TensorFlow Developer Certificate plugin into PyCharm. I go to PyCharm Plugins and search for "TensorFlow", but there's no TensorFlow Developer Certificate plugin available.
PyCharm Plugin Search Screenshot
I have installed four different versions of PyCharm because I thought it was a version problem, but the TensorFlow Developer Certificate plugin cannot be found in any of the four versions:
pycharm-community-2021.1.1.exe
pycharm-community-2020.3.5.exe
pycharm-community-2020.1.5.exe
pycharm-community-2019.3.5.exe
Am I supposed to do something else to be able to see this plugin in the search? Thanks so much in advance for your assistance.
I solved the problem by manually downloading the TensorFlow Developer Certificate exam plugin at:
https://plugins.jetbrains.com/plugin/13812-tensorflow-developer-certificate
I then extracted it to this directory:
C:\Program Files\JetBrains\PyCharm Community Edition 2021.1.1\plugins
It's strange that it had to be manually installed though. The exam manual states that all you have to do is look for the plugin at the PyCharm Plugin Marketplace.

WSO2 Developer Studio Nullpointer exception

I am using WSO2 Developer Studio latest version 3.8.0 on Mac OS High Sierra. Each time when I drag and drop element from the tool pallet into the design workspace, It shows Null pointer exception. Also canvas title is not visible. Here below I attached a screenshot. So much appreciate your help.
Nullpointer exception
I also face similar issue since I install both Oracle JDK 8 and JDK 10. Eclipse take latest JDK 10 version, but application does not support Java 10. To select Java version to use, I added following line into the /Applications/Eclipse.app/Contents/Eclipse/eclipse.ini file. Then it work fine.
-vm
/Library/Java/JavaVirtualMachines/jdk1.8.0_171.jdk/Contents/Home/bin
If you are using Java 10 then you can remove it and install Java 8 or you can use both version and update eclipse.ini file to point JDK 8 version.
Hope this will be helpful.

Installing Glassfish tools in eclipse luna

Im trying to install Glassfish tools in eclise Luna but I keep getting this error message:
Cannot complete the install because one or more required items could not be found.
Software being installed: GlassFish Tools 7.3.3.201412231459 (oracle.eclipse.tools.glassfish.feature.group 7.3.3.201412231459)
Missing requirement: GlassFish Tools 7.3.3.201412231459 (oracle.eclipse.tools.glassfish.feature.group 7.3.3.201412231459) requires 'org.eclipse.sapphire.feature.group [8.1.0,8.2.0)' but it could not be found
What should I do? Thanks.
It looks like they somehow messed up the plugin dependencies while packaging the plugin version which is currently referenced by the .
To fix it you have to install an slightly older version of the Glassfish Tools manually. To do this in Eclipse click on Help -> Install new software and put the following URL in the upper input field:
http://download.oracle.com/otn_software/oepe/12.1.3.1/luna/repository
Then click enter, after it has fetched the installable packages, choose the Glassfish Tools package and the Oracle Java EE Tools package (both should be version 7.2.0.xxx) and install. The installation can take a while because the oracle repository site is often slow.

Cannot see the Glassfish adapter after installing plugin in Eclipse

I've installed Glassfish 3.1.1 and Eclipse Indigo onto a Win 7 machine but cannot add the Glassfish server via Eclipse's Servers view.
Oracle Glassfish Server Tools 1.8 is also installed but despite this there is no Glassifish entry in the list of avilable server adaptors.
I will continue to scour the web for a way around this but if anyone can advise I'd be grateful.
Thanks
You need to install the JavaEE development edition of Eclipse, and in that go to the Eclipse Marketplace where you can find and install the Glassfish adapter.
I had to restart eclipse two times before it appeared. This seems like a bug to me but I'm new in the Eclipse world
