Setting Up Dev-Environment with SDK2.1

[jogla]

Hello,
I made several trials to set up a development environment in order to follow the tutorials by Jeff Pott [ http://ecmarchitect.com/alfresco-developer-series ].
I always get stuck at the same Point.

In our company I am sitting behind a proxy/frewall. I managed to get through it by using a CNTLM-Service on my Computer.
As you see in the file [ https://docs.google.com/document/d/15uRRmT2kwjrkRrSOmAnvOyf8_41ehoxiw6IJA1KW-Xo/edit?usp=sharing (shortened logfile) / full file: see the attached textfile] at first all went well:
mvn –Version …OK.
mvn archetype:generate -Dfilter=org.alfresco:  …OK.

but when ist come to
mvn install
the download process gets stuck with several errors. Always at the same position.
…
[ERROR] [ERROR] Some problems were encountered while processing the POMs:
[ERROR] Unresolveable build extension: Plugin org.alfresco.maven.plugin:alfresco-maven-plugin:2.1.0 or one of its dependencies could not be resolved: Failed to collect dependencies at org.alfresco.maven.plugin:alfresco-maven-plugin:jar:2.1.0 -> org.alfresco:alfresco-mmt:jar:5.0.d @
[ERROR] Unknown packaging: amp @ line 9, column 16
…


=> Can anyone see what the probelm is?
=> What's the best way to analyze?
=> Is there a way to download the whole package (with all dependencies)?

Best regards,
Joerg Glasauer

It looks like you cannot download from https://artifacts.alfresco.com. So your Java installation might not have correct CA path to artifacts cert.

Try using the following class to test this, you should see something like:

martin@gravitonian:~/tools$ java SSLPoke artifacts.alfresco.com 443
Successfully connected

You can download this class from for example: https://confluence.atlassian.com/display/JIRAKB/Unable+to+Connect+to+SSL+Services+due+to+PKIX+Path+B...

Thank you Martin.
after downloading and using the additional class I'm getting the following back:

C:\Daten\AlfSDK21TutorialHome>java SSLPoke artifacts.alfresco.com 443

Just tried to connect with curl an got the following back:

curl: (60) SSL certificate problem: self signed certificate in certificate chain
More details here: http://curl.haxx.se/docs/sslcerts.html

curl performs SSL certificate verification by default, using a "bundle"
 of Certificate Authority (CA) public keys (CA certs). If the default
 bundle file isn't adequate, you can specify an alternate file
 using the –cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
 the bundle, the certificate verification probably failed due to a
 problem with the certificate (it might be expired, or the name might
 not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
 the -k (or –insecure) option.

I looked at the traffic with whireshark there are only 3 short connections from my computer to "162.13.213.78" an nothing comes back.
I think I speak to our firewall admin?

Or is there a way to download the whole package from outside of our Company network and bring the full set inside ("manually")=> Then: what parts do I have to take?

:-j,
Joerg

[gravitonian]

Hi,

I think you need to get your network admin to open up the connection to the Alfresco Nexus server (Maven repo). It is not practical to start downloading all artifacts and then install them manually in your local maven repo. You might also make sure that the Maven central repo is accessible (http://repo1.maven.org/maven/)

[jogla]

I hope they'll support me.

Thank you Martin!
