问题
I am new to UIMA Ruta and I am currently trying to get a simple HelloWorld script to run. I followed the instructions here to set up my HelloWorld project.
The first error that occured was java.lang.NoClassDefFoundError: org/slf4j/event/Logger which I resolved by converting my project to a maven project and adding the slf4j-api 2.0.0-alpha1 and ruta-core 2.7.0 dependencies to pom.xml.
Now, my HelloWorld script generates an output file to the output folder. But when I try to open it with the UIMA Annotation Editor it says "Editor could not be initialized." with the following details:
java.lang.NullPointerException

The same thing happens when I try to open the ExampleProject in the example-projects folder of the UIMA Ruta project. I know about this question here but it didn't solve my problem.
What am I doing wrong?
回答1:
At the moment there is no UIMA Ruta Version compatible with UIMA v3. Try downgrading the UIMA Version to 2.10.4 (for instance). For more info please refer to this question.
