Sam Uong's recommendation of switching the PKCS12 keystore type to JKS fixes the InvalidAlgorithmParameterException.
I experienced this bug while using both openjdk-1.8-jdk and default-jdk package installs on Ubuntu 18.04. For those that might similarly discover this bug when attempting to run their gradle builds, you need to: 1. Follow Sam Uong's post above 2. Kill all gradle processes 3. Re-run your gradle build scripts I figure this small bit of text may be indexed and help others that narrow their search on gradle. -- You received this bug notification because you are a member of OpenJDK, which is subscribed to openjdk-9 in Ubuntu. https://bugs.launchpad.net/bugs/1743139 Title: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty Status in openjdk-9 package in Ubuntu: Confirmed Bug description: When trying to access anything using Java + HTTPS, the process is terminated with an java.security.InvalidAlgorithmParameterException. Adding -Djavax.net.ssl.trustStorePassword=changeit to the command line flags of java fixes this problem. Either the trust store's password should be changed, or this flag sould be added by default.
