Echoing all the environment properties

[Mike Curwen]

Can this easily be done?

  <property file="SystemBuild.properties" />
  <property environment="env"/>
  <property name="catalina.home" value="${env.CATALINA_HOME}" />
  .
  .
  .
  <echo>HOST: ${env.HOSTNAME}</echo>
  <echo>version.major: ${version.major}</echo>
  

I've recently switched environments (Suse to Ubuntu) and now my env.HOSTNAME appears to be empty. The version.major property is there, it's being loaded from the SystemBuild.properties file.

At the command line, I type 'set', and within that listing, I see a HOSTNAME defined.

I'm just wondering if anyone's experienced this problem before on Ubuntu (or other platform)

Also: is it possible to have Ant iterate over all "env." properties ? That is: Find out what gets loaded by : property environment="env"


Thanks.

Mike,
Take a look at the echoproperties task. You can supply a prefix to get a subset of the properties - the env ones - or no prefix to get them all.

doh!

It never even occured to me to search the Ant docs directly.

One would *think* that googling for "ant echo properties", would have found this page

Thanks very much!
