Error on starting spring boot 3 EAR on Websphere Liberty

Question

I am upgrading my spring boot application to version 3 and Java 17. I have already installed Java 17 liberty patch on websphere liberty server and enabled few features in server.xml like below

<featureManager>
<feature>servlet-6.0</feature>
<feature>ssl-1.0</feature>
<feature>ldapRegistry-3.0</feature>
<feature>zosLocalAdapters-1.0</feature>
<feature>zosTransaction-1.0</feature>
<feature>jdbc-4.3</feature>
<feature>jndi-1.0</feature>
<feature>springBoot-3.0</feature>
<feature>monitor-1.0</feature>
<feature>mpMetrics-5.0</feature>
<feature>enterpriseBeans-4.0</feature>

but when I trying to deploy my spring boot ear to server. it is throwing an exception

    Caused by: java.lang.ClassNotFoundException: CWWKL0084W: The javax.transaction.Synchronization class could not be loaded. Try enabling the jdbc-4.0 feature or a newer version of the feature in the server.xml file.

below are the dependacies of my spring app

}

I tried following after searching over internet

1. Added jta dependancy in gradle but did not work
2. Added persistence-1.0 and not luck

I have almost exhausted with options so seeking some expert help here.

Answer 1

So, Just to summarise the solution of issue & As Hakan rightly said it was indeed dependencies relay issue.

I excluded problematic one from gradle using exclude and that resolved my problem.

implementation('com.ibm.websphere.appserver.features:zosLocalAdapters-1.0:24.0.0.1') {
        exclude group: 'javax.transaction', module:'jta'
        exclude group: 'javax.transaction', module:'javax.transaction-api'
    }
