Answer 1

Next time, please include your build.gradle file.
I believe your problem is caused by the fact you are trying to apply the plugin:'org.springframework.boot' without telling your gradle script where to find that plugin. Your buildscript (build.gradle file) actually depends on the org.springframework.boot plugin, however since it can't find it (and doesn't even know what it is), you are getting this issue.
you can fix that issue by adding the following code at the top of your file:
buildscript {
repositories {
mavenCentral()
}
dependencies {
// You are telling gradle that this script (Not the project) depends on the
// following plugin
classpath "org.springframework.boot:spring-boot-gradle-plugin:2.1.2.RELEASE"
}
}
apply plugin: "org.springframework.boot"
// The rest of your build.gradle file

I had the same problem, so I changed to Gradle 6.5 and also add settings.gradle file in the same dir as your build.gradle with the following info.
// settings.gradle
pluginManagement {
plugins {
id "org.springframework.cloud.contract" version "${verifierVersion}"
}
repositories {
// to pick from local .m2
mavenLocal()
// for snapshots
maven { url "https://repo.spring.io/snapshot" }
// for milestones
maven { url "https://repo.spring.io/milestone" }
// for GA versions
gradlePluginPortal()
}
}
In addition make sure that you can connect to your repositories. In my case if was a internal nexus server and gradle wasn't able to connect to the repositories because of SSL certificate missing from JDK truststore. I added the nexus SSL certificate in to the JDK truststore and it resolved
