Eclipse 2018-12 cannot install Tomcat plugin [message #1800672] Fri, 04 January 2019 16:34 Go to next message

Currently it is January 2019. From the Eclipse web site people can download the latest Eclipse IDE, known as 2018-12. In our case, we downloaded for Windows 64-bit. The installation for Java development is fine, for Java 11. However, one cannot install Tomcat plugin. Here are the steps to reproduce.
Open IDE, meaning Eclipse 2018-12.
Go to Help / Eclipse Marketplace ..
Search for Tomcat Plugin.
Install any plugin tool and it will fail.

Example 1: Install Uqbar Tomcat XT Eclipse Plug-in 2.0.0, it failed because of authentication error. One can install anyway and go to Window / Preferences, click Tomcat, error happened.

Example 2: Install Eclipse Tomcat Plugin 9.1.3, and error came out right away.

This did not happen in Eclipse Photon (released in June 2018).

So the question is how to install Tomcat plugin into Eclipse 2018-12. By the way, we manually downloaded Eclipse Tomcat Plugin 9.1.3. Then the question is how to manually install it into Eclipse? We tried but with no luck.

If I recall correctly, market place client has problems running on Java 11 because some javax packages have been removed from Java 11. So I think the only workaround is to make sure you have a Java 8, 9, or 10 installed, and to use that to run the IDE, e.g. , add/modify the following lines in the eclipse.ini:
-vm
C:/Program Files/Java/jdk1.8.0_121/bin
Make sure these are before the -vm args section and that they are on two separate lines as illustrated. Within that IDE you can still use Java 11 as your JRE via Window -> Preferences -> Java -> Installed JREs.

Thanks. Actually the problem is not regarding how to configure Java 11 and create a JAVA project in the IDE. That works fine. We can create JAVA project using Java 11 and run smoothly.
The problem is not able to install Tomcat plugin, either manually or through Eclipse Marketplace. Without such plugin, this IDE cannot be used to create Tomcat project.

The solution is NOT to download and install this "pure" Windows 64-bit release (known as 2018-12). Instead, download eclipse-jee-2018-12-R-win32-x86_64.zip (known as 2018-12-R) and install. Then manually install Tomcat plugin. This worked.
Conclusion:
Eclipse Marketplace does not work because of Java 11. But to install a plugin manually, The 2018-12 release does not work, but 2018-12-R works. In other words, to use Java 11 and Tomcat, currently downloading and installing which Eclipse has a difference.

The Eclipse IDE for Enterprise Java already includes support for launching dynamic web projects with Tomcat. If that's all that's needed, you don't need an additional plug-in.
