Eclipse(HANA Development): Error when searching for a table in aProjection Node of a Graphical View

[mitko1994]

I have Eclipse Version: 2024-12 (4.34.0) with the latest SAP Development tools installed

I want to create a Calculation View and add a table to a Projection Node, but whenever I search for the table name, I get the following error. How can I fix this?

Here is the full error log

I have the same issue. Please let me know if you find the solution.

As a potential workaround, use the web based repository editor to add the source tables . So far I am doing that

My case is a bit different, but I ended up with the same problem and found a way to solve it.

As has been mentioned, version 2024-12 is not supported, so you should install one of the supported ones (the latest being 2024-9). The issue is that I made a mistake and installed version 2024-12, which gave me this error. From that point on, I spent three weeks trying every imaginable way to uninstall Eclipse and reinstall different versions, but the error persisted.

I analyzed the error log and found on Stack Overflow that the problem is caused by the presence of two plugins with different versions:

org.apache.commons.commons-logging_1.3.4.jar
org.apache.commons.logging_1.2.0.v20180409-1502.jar

They are located in the ..\eclipse\plugins folder.

Since Eclipse is self-executable, managing libraries is straightforward. I renamed the more recent one—without much hope, I might add—and to my surprise, it works correctly.

I understand that the definitive solution should come from SAP, but in the meantime, this can serve as a workaround. I did this a few days ago, and so far I haven’t encountered any other error or problem.

Try it and see if you’re lucky.

Hi, thanks a lot for this hint. In you case, how did you rename the most recent one ? I've seen only one duplicated JAR in my folder, which is the logging_1.2.0

[mitko1994]

Thanks for the detailed response. Unfortunately, I only see one of each of these .jar files, so I guess I don't have duplicates or different versions

[lkysiak]

Hi, I'm expanding on your answer because you didn't say exactly how you changed the file name. All you need to do is rename the file from "org.apache.commons.commons-logging_1.3.4.jar" to "org.apache.commons.commons-logging_1.2.0.jar". In my case it solved the problem.

Hi lkysiak, I'm glad that you have also fixed your problem. I only kept one plugin—the old one: org.apache.commons.logging_1.2.0.v20180409-1502.jar. When I say that I renamed the more recent one, I mean that I changed its extension so that Eclipse wouldn't find it: org.apache.commons.commons-logging_1.3.4.jar.old
