Cannot build Liferay portal 7.0.2 from source code

[Fahmi Bedoui, modificado 7 Anos atrás.]

Hello,
I need to compile Liferay locally (for a little useful modification), I use 7.0.2-ga3.
I downloaded the source code of liferay portal from github and I followed this link to build the product, but It fails to compile (failed even to clean "ant clean")


The exception is:

You're failing in trying to hit the Liferay CDN repository where the artifacts are hosted. Are you sitting behind some sort of proxy?








Come meet me at the LSNA!

[Fahmi Bedoui, modificado 7 Anos atrás.]

Yes, but I have configured the proxy for Ant.
I am under windows and I have set the variable ANT_OPTS
ANT_OPTS => -Xmx1024m -XX:MaxPermSize=512m -Dhttp.proxyHost=our_proxy_host -Dhttp.proxyPort=8080

Is this the corerct way to do ?

Thanks

So if you google for "liferay ant proxy settings" you'll find a bunch of different forum posts, etc., that may offer solutions.

The tough part is that most of these examples are going to be for changing the SDK and such, not really how to compile from source. As Liferay is building the CE version, I don't believe they have ever felt the need to integrate and/or test using a proxy to build the portal.

So basically you may be on your own trying to figure out how to do it...

I have successfully build it, after experiencing the same error as above. Just want to share, in case someone out there having this error, just chill out.

My internet was fine, so I suspect that there was something wrong with the Liferay cdn "https://cdn.lfrs.sl" at one moment, and the next moment I was able to ping or telnet the server, everything worked fine.
