I created fat jar with groupdocs-metadata-24.12.jar to add keywords to docx file. Got the error message :
at com.groupdocs.metadata.core.MetadataAssemblyConstants.getInstance(Unknown Source) | |
---|---|
at com.groupdocs.metadata.licensing.License.setLicense(Unknown Source) |
Caused by: java.lang.NullPointerException

How to fix the problem? Thanks.
