I was missing the following from my build.gradle:
jacoco {
toolVersion = "0.8.6"
}
While obvious, build.gradle can inherit properties from other gradle files and for reasons I can't figure out, jacoco was passing through in to one subproject but not to another.
Ensure you are using JDK-11, if using maven, ensure;
<maven.compiler.source>11</maven.compiler.source>
<maven.compiler.target>11</maven.compiler.target>
Ensure you are using latest jacoco.
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
<version>0.8.4</version>
Fixed this error changing Java SDK in my project from 14 to 11 and my tests started working fine.
Solution: IntellijIDEA: File > Project Structure > Project Tab > SDK adopt-opendjdk-11 (in my case for Ubuntu).
Oh! Make sure Gradle Settings are also using the same JVM!
Hope that helps someone out there.
I had similar issue when I upgraded my jdk1.8 to openjdk11 but it was solved by updating the toolVersion = "0.8.6" (used toolVersion = "0.8.1" with jdk1.8)
The issue comes from the Java version which needs not to be too recent.
sdk install java 19.3.0.2.r8-grl
makes things ok.
After followed below steps it's working fine for me.
In Eclipse,Go to Window--Preferences--java.Right-click on installed JRE. There add an installed JDK path & remove others.
Fix in my case was to download and install Java 8 (jdk1.8.0_301) and set it in Project Settings
