mvn exec:exec installation error

[DollyCM]

Hi,
I am trying to install RNArtist on Ubuntu 20.04 with following jdk version:
openjdk version "11.0.18" 2023-01-17
OpenJDK Runtime Environment (build 11.0.18+10-post-Ubuntu-0ubuntu120.04.1)
OpenJDK 64-Bit Server VM (build 11.0.18+10-post-Ubuntu-0ubuntu120.04.1, mixed mode, sharing)

As mentioned, I have changed the java.version in pom.xml to 11.0.18.

mvn clean package works successfully with the following build success:

But, the next exec command fails with a build failure. The log is as follows:

Having the same issue. Did you resolve it, if so how?

Hi,
Not yet. I got occupied with other things so I have not looked at it again. But I was suggested to do the following.
Try installing with OpenJDK and JRE 7 version.

Do let me know if it works for you!
All the best,
Dolly

That did not work for me. The problem might be with the plugin itself?

Hi, I've encountered the same issue before, and I resolved it by updating to JDK 17. Alternatively, you can try modifying the pom.xml file as follows:

<java.version>17</java.version>
<javafx.version>17.0.2</javafx.version>

This will set the Java version to 17 and the JavaFX version to 17.0.2 in the pom.xml file.
