I have a strange problem which prevents my Grails 3.3.9 app from starting up after deployed to a Tomcat 8.
Until recently, we had our own copy of a JasperService. We have removed this and are now using the Jasper Plugin. Alas, now we are getting an exception (ff being our app)
org.grails.taglib.TagLibraryLookup.registerTagLib(TagLibraryLookup.java:113)
...
org.springframework.beans.ConversionNotSupportedException: Failed to convert property value of type 'ff.documents.JasperService' to required type 'grails.plugins.jasper.JasperService' for property 'jasperService'; nested exception is java.lang.IllegalStateException: Cannot convert value of type 'de.berlinale.ff.documents.JasperService' to required type 'grails.plugins.jasper.JasperService' for property 'jasperService': no matching editors or conversion strategy found
As we do not have a TagLib injecting the JasperService, I presume that there is somewhere still a memory of / reference to the old service which actually tries to get injected into the JasperTagLib of the Plugin, which I can not edit:
class JasperTagLib {
JasperService jasperService
...
}
I am using IntelliJ Ultimate 2018.3 and the problem does not occur locally, but only on deployment as a war to the tomcat. I have searched in path and scope for the string but have not found anything.
I would be glad if someone could hint me in the direction where to look for this phantom.
We found this to possibly have been a Git problem. We branched the master and deployed this without any changes and it started up no prob, so we presume it actually was a corrupt Git repo of our master branch. I guess @injecteer was right that it must have contained a reference.
I'll give my question the git tag. Thanks @injecteer
