Upgrade to spring-geode-starter 1.4.2 produces condition, introspection and ClassNotFoundExceptions

Question

On return to a Geode reactive streams project after some time I would like to upgrade to latest spring-geode-starter. Perhaps related to Spring Boot Geode Unsatisfied dependency expressed through method 'sessionRegion' also on ClientCacheConfiguration what I think is a simple build.gradle dependencies gives exception:

Answer 1

I am not exactly sure how (reviewing your dependencies in the Gradle build shown above), but the NoClassDefFoundError/ClassNotFoundException on the Apache Geode API class org.apache.geode.cache.client.SocketFactory is caused by an incompatible version of Apache Geode (i.e. a version prior to 1.13).

The SocketFactory class was in fact introduced in Apache Geode 1.13 (see here, then try here).

Indeed SBDG 1.4.2 pulls in SDG 2.4.3, which is based on Apache Geode 1.13.1. This is also apparent from the SBDG Version Compatibility Matrix.

You might try running:

$ gradlew dependencies | less

And searching for all the org.apache.geode:geode-core dependencies (simply search for "geode-core") and see which versions of Apache Geode are being used, overridden, etc.

But, anytime you see a NoClassDefFoundError/ClassNotFoundException or NoSuchMethodError, errors of that nature, you can bet that 9 out of 10 times you have a version problem.

Answer 2

This was solved by checking out the Version-Compatibility-and-Support-Matrix and selecting

implementation 'org.springframework.geode:spring-geode-starter:1.2.8.RELEASE'
