am a newbie with Liferay on Eclipse, each time i try to carete a new liferay module project i get the following error. Am running Ubuntu 18.
Synchronize Gradle projects with workspace failed due to an error connecting to the Gradle build. Could not install Gradle distribution from 'https://services.gradle.org/distributions/gradle-3.0-bin.zip'.
Caused by: javax.net.ssl.SSLException: java.lang.RuntimeException: Unexpected error: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty
I found a solution, here, there are many solutions so i will paste the exact one that did it for me.
First remove conflicting packages:
sudo apt-get remove --purge openjdk* java-common default-jdk
sudo apt-get autoremove --purge
Check weather you successfully removed all related packages by:
sudo update-alternatives --config java
The system shall prompt you there is no Java available to config, otherwise this workaround fails.
Then reinstall required packages:
sudo apt-get install openjdk-8-jdk
