  • How to Ignore an Invalid SSL Certificate in Java

    Sometimes during development it is useful to use a certificate whose CN (Common Name) does not match the host name in the URL, for example localhost. In these cases Java will throw an SSLHandshakeException. How can we easily disable certificate checking for localhost and other domains of our choosing?

The problem was I couldn’t add those settings to a file in the standard src/groovy/resources folder, because when creating a distribution with Gradle ./gradlew distZip the file would be part of the jar, and thus it would be difficult to modify the contents. I was basically after a run-control file, a settings file in the root of my distribution, that I could easily change on each run (if necessary).
