I've just installed 17.10 in a fresh VM. Trying to set up a development environment, when I run
./gradlew I get the following error:
* What went wrong: Error resolving plugin [id: 'com.github.johnrengelman.shadow', version: '2.0.0'] > Could not GET 'https://plugins.gradle.org/api/gradle/4.0/plugin/use/com.github.johnrengelman.shadow/2.0.0'. > java.lang.RuntimeException: Unexpected error: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty
This is irrespective of gradle version, java version (both openjdk and oracle 8 and 9 have the fault) and shadowjar version. This leads me to the conclusion that it is Ubuntu related rather than gradle/openjdk/oracle related.
I've tried updating the CA certificates, both
sudo update-ca-certificates -f and
sudo apt install ca-certificates-java --reinstall, neither of which solves the problem. I even reverted to the tried and tested turn it off and on again technique with no affect.
What's the problem and how do I fix it?
