java.lang.IllegalStateException: Error processing condition on org.springframework.boot.autoconfigure.jdbc.JndiDataSourceAutoConfiguration

This is caused by non-matching Spring Boot dependencies. Check your classpath to find the offending resources. You have explicitly included version 1.1.8.RELEASE, but you have also included 3 other projects. Those likely contain different Spring Boot versions, leading to this error.

I know this is quite an old one, but I faced similar issue and resolved it in a different way. The actuator-autoconfigure pom somehow was invalid and so it was throwing IllegalStateException. I removed the actuator* dependencies from my maven repo and did a Maven update in eclipse, which then downloaded the correct/valid dependencies and resolved my issue.

In my case I had created a SB app from the SB Initializer and had included a fair number of deps in it to other things. I went in and commented out the refs to them in the build.gradle file and so was left with:

implementation 'org.springframework.boot:spring-boot-starter-hateoas'compileOnly 'org.projectlombok:lombok'developmentOnly 'org.springframework.boot:spring-boot-devtools'runtimeOnly 'org.hsqldb:hsqldb'runtimeOnly 'org.postgresql:postgresql'annotationProcessor 'org.springframework.boot:spring-boot-configuration-processor'annotationProcessor 'org.projectlombok:lombok'testImplementation 'org.springframework.boot:spring-boot-starter-test'testImplementation 'org.springframework.restdocs:spring-restdocs-mockmvc'

as deps. Then my bare-bones SB app was able to build and get running successfully. As I go to try to do things that may need those commented-out libs I will add them back and see what breaks.
