= Maven Repository = We have our own Maven repository exclusively for mod development located at [https://gauss.extollit.com/mvn] (and nothing else). This may become necessary one day when Forge and/or Mojang shuts down their servers for these legacy artifacts. == SSL Woes == In order to use the repository in Gradle it may be necessary to install our certificate to your central trust store. Follow the steps below: === Step 1 - Obtain the root certificate === The root certificate is the same one serving-up this web-page, so use your browser to find out what it is and where to get it. We're not going to link it or attach it here directly because that is a security risk. === Step 2 - Convert the root certificate to DER format === This can be done with help of the **openssl** toolkit, where `gd-bundle.pem` is the original certificate filename in PEM format, and `gd-bundle.der` the filename to output, in DER format (which the Java keytool utility can understand). If you were able to obtain the root certificate in DER format, skip this step. {{{ #!sh openssl x509 -in gd-bundle.pem -inform pem -out gd-bundle.der -outform der }}} === Step 3 - Validate the root certificate content === Ensure that the Java keytool can parse the certificate and display its content: {{{ #!sh keytool -v -printcert -file gd-bundle.der }}} === Step 4. Import the root certificate into the JVM trust store === Enter the following command where `$JAVA_HOME` is a shell environment variable that points to your Java installation, e.g. to `/usr/lib/jvm/java-8-oracle`; for `-alias` pick some unique name for the certificate in the store: {{{ #!sh keytool -importcert -alias startssl -keystore $JAVA_HOME/jre/lib/security/cacerts -storepass changeit -file gd-bundle.der }}} (the default password for the CA store is ''changeit'') The keytool will prompt you for confirmation, enter ''yes'' to complete the operation. === Step 5. Verify that the root certificate has been imported === To do that list the trust store content and filter for the certificate alias (name) with `grep`: {{{ #!sh keytool -keystore "$JAVA_HOME/jre/lib/security/cacerts" -storepass changeit -list | grep '^startssl\b' }}} You will now be able to make secure SSL/TLS connections to servers which have a certificate signed by the CA which we just imported. == Even More SSL Woes == You may have to explicitly declare the Maven ''central'' repository as an SSL endpoint, add this to your custom user-specific Maven settings (usually goes in `~/.m2/settings.xml`): {{{ #!xml central HTTPS Central Repository https://repo1.maven.org/maven2/ central }}}
