------------------------------------------------------------
I'm also experiencing this issue with maven 2.2.1 with a Nexus server on the
back. I have sniffed the http communications and the preemptive authentication
configuration is indeed being ignored.
Furthermore it appears that the expect 100-continue functionality isn't working
properly either. Protocol inspection reveals that even when 100-continue is
sent in the header the payload is still sent. Naturally this leads to a bad
checksum computation on the server since the first request is denied with 401
since preemptive authentication doesn't work.
Note: We are using a username and maven encrypted password in the server
section of settings.xml.
Here is an excerpt with the password altered of course.
<server>
<id>nexus-server</id>
<!-- configure windows domain username and encrypted password here
Don't forget you need to setup a settings-security.xml file too in the same
directory for password decryption purposes.
-->
<username>ctanger</username>
<!-- This may not be a valid base64 string since it was altered -->
<password>{CJ9S6SY2mSAH3w5CheexecNxNxd/nqZ3Wkef1a1a5Kg=}</password>
<configuration>
<wagonProvider>httpclient</wagonProvider>
<httpConfiguration>
<all>
<params>
<param>
<name>http.authentication.preemptive</name>
<value>%b,true</value>
</param>
</params>
</all>
</httpConfiguration>
</configuration>
</server>
