Grails

I don't see how the proposed solution is workable since we don't currently depend on commons-ssl or commons-httpclient. Seems a bit brute force to introduce a new dependency to solve the problem

We may have to use Commons HttpClient so that Ivy can work against repositories that require authentication. I thought there was a related issue, but I can't find it.

I wonder if there is a way to test this, maybe adding the codehaus repository using https:// as a protocol?

I'm not sure this is something we can do with automated tests. Adding dependencies to external servers is asking for trouble. We could include some tests as part of a manual step (automated running of tests, but requiring manual initiation). Perhaps we could use VMs to help here? Create a VM image with Artifactory and a Subversion repository set up, then run the tests against that. Once the tests have completed, revert back to the original image.

This problem was made worse by the fact we were publishing plugin download URLs with HTTPS instead of HTTP which has been fixed by this commit:

Stefan gets this output with HEAD when publishing a plugin from Ubuntu:

Note that the plugin was successfully released once the plugin list was rebuilt. It seems that SvnKit has no problem with Codehaus' new certificate, I suspect because it doesn't require SSL certificates to be trusted, simply valid.

It would be good to fix the problem with the plugin list though. There's no need to fetch it via SSL.

At least for Ubuntu Lucid: Ubuntu manages cacertificates by package ca-certificates and ca-certificates-java. These packages store the ca certs in /etc/ssl/certs/java/cacerts. But java-6-sun basically uses /etc/java-6-sun/security/cacerts. So when symlinking /etc/java-6-sun/security/cacerts to /etc/ssl/certs/java/cacerts the SSL exception is gone.

Importing StartCom certificates in unix:

wget http://www.startssl.com/certs/ca.pem
wget http://www.startssl.com/certs/sub.class2.server.ca.pem
keytool -import -alias StartComCA -keystore $JAVA_HOME/jre/lib/security/cacerts -storepass changeit -file ca.pem
keytool -import -alias StartComClass2PrimaryIntermediateServerCA -keystore $JAVA_HOME/jre/lib/security/cacerts -storepass changeit -file sub.class2.server.ca.pem

Testing from command line:

groovy -e "println new URL('https://svn.codehaus.org/grails-plugins/.plugin-meta/plugins-list.xml').openConnection().date"

In Cygwin on Windows, same commands as Lari's above, except make sure you surround the $JAVA_HOME with ""

keytool -import -alias StartComCA -keystore "$JAVA_HOME/jre/lib/security/cacerts" -storepass changeit -file ca.pem

keytool -import -alias StartComClass2PrimaryIntermediateServerCA -keystore "$JAVA_HOME/jre/lib/security/cacerts" -storepass changeit -file sub.class2.server.ca.pem

Tomas, did you get an SSLHandshakeException when trying to publish your plugin? I'm trying to work out whether this is still an issue or not. There should be no reason for users to get the SSHandshakeException any more.

Peter, yes, I got the SSLHandshakeException on both Grails 1.3.3. and Grails 1.3.4 on Windows Vista. My JDK version is

java version "1.6.0_18"
Java(TM) SE Runtime Environment (build 1.6.0_18-b07)
Java HotSpot(TM) Client VM (build 16.0-b13, mixed mode, sharing)

and my environment is Windows 7 Home Premium.
