I am working on STS and while creating a new spring-boot project, it shows following error:
SunCertPathBuilderException: unable to find valid certification
Adding below to eclipse.ini
-Djavax.net.ssl.trustStore=C:\Program Files\Java\jdk1.8.0_20\jre\lib\security\cacerts -Djava.net.ssl.trustStorePassword=changeit
worked for me.
