The SSL Connection to our company nexus repository is secured and we need to provide a client certificate to connect to our repository via https
Our client certificate is installed on a pkcs11 token (usb stick, Feitian PKI).

With 1.0-milestone-5 we can put these lines to the gradle wrapper script ./gradlew:
DEFAULT_JVM_OPTS=" \
-Djava.security.debug=sunpkcs11 \
-Djavax.net.ssl.trustStore=NONE \
-Djavax.net.ssl.trustStoreType=pkcs11 \
-Djavax.net.ssl.keyStore=NONE \
-Djavax.net.ssl.keyStoreType=pkcs11 \
"

With 1.0-milestone-5 it does work in gradle, too. But not in 1.0-milestone-6 and upwards (i tested 1.0-milestone-9 and rc-1)

gradle (or whoever) asks still for the PIN of my token but when it comes to downloading it does not work.

It seems to be related to http://issues.gradle.org/browse/GRADLE-1971
as gradle switched from java.net.URL to another lib which does not respect these system properties.

For me it is a blocker, but for the majority this might be a minor bug. But i guess it will even not work if you have a keystore on your disk which is far more common maybe.

I am eager to help you on this topic. Please tell if i can send you more information or test a new release.
