Ant tasks does not support updatePolicy correctly
-------------------------------------------------
Key: MNG-2752
URL: http://jira.codehaus.org/browse/MNG-2752
Project: Maven 2
Issue Type: Bug
Components: Ant tasks
Affects Versions: 2.0.4
Reporter: Chris Hilton
Attachments: build.xml
Attached is an example build.xml file. The relevant line is:
<snapshots enabled="true" updatePolicy="never"/>
I completely remove the com.alterpoint.thirdPart:example directory from my
local repository and, in a separate project, I build a
com.alterpoint.thirdParty:example:6.0-SNAPSHOT artifact and install it back
into the local repository so it's the only version there. With regular Maven,
because I have a locally installed snapshot and updatePolicy=never, nothing is
downloaded and it references that snapshot directly. When I run the attached
build file, though, I get the following output:
F:\Temp\scratch>ant
Buildfile: build.xml
[INFO] snapshot com.alterpoint.thirdParty:example:6.0-SNAPSHOT: checking for
updates from central

dist:
[copy] Copying 1 file to F:\Temp\scratch
BUILD SUCCESSFUL

F:\Temp\scratch>
The Maven Ant tasks for some reason decide to download and update over my local
SNAPSHOT even though updatePolicy=never is specified. Subsequent build
deployments of that artifact remotely do not get downloaded, even if I rebuild
a local SNAPSHOT. Only the first local SNAPSHOT, when it's the only SNAPSHOT,
seems to cause this behavior. Unfortunately, that's a pretty common occurrence
with our build system.
