I have java , java development kit 32 bit and 64 bit installed on my laptop. I have installed apache maven 3.6.3 and its path is C: \Program Files\apache-maven-3.6.3. I have downloaded chemistry development kit cdk-2.0.jar and it is Program Files directory.
On my laptop, JAVA_HOME environment variable is set to C:\Program Files\Java\jdk-15.0.1. But at the time of installation of cdk-2.0.jar by giving command mvn install at the command prompt, following screen appears.
How to overcome this difficulty?
