copy does not fetch most recent snapshot when -U is set
-------------------------------------------------------
Key: MDEP-276
URL: http://jira.codehaus.org/browse/MDEP-276
Project: Maven 2.x Dependency Plugin
Issue Type: Bug
Components: copy
Affects Versions: 2.1
Environment: Apache Maven 3.0-beta-1 (r935667; 2010-04-19
19:00:39+0200)
Java version: 1.6.0_18
Default locale: en_IE, platform encoding: Cp1252
OS name: "windows vista" version: "6.0" arch: "x86" Family: "windows"
Reporter: Tobias Oberlies
Assignee: Brian Fox
The {{copy}} goal seems to ignore the {{-U}} command line option. With the
configuration below and {{-U}} set, the most recent snapshot of an artifact is
not fetched if there is a reasonably new (in my case a few hours) snapshot
version cached in the local repository. This is not sufficient. Afaik {{-U}} is
supposed to force the check for new snapshot versions.
When I delete the local snapshot artifact, the MOJO logs the message
{noformat}
[INFO] snapshot example-group:example-artifact:0.1.0-SNAPSHOT: checking for
updates from example-nexus
{noformat}
However no such line is printed out when there is an outdated local snapshot
artifact and {{-U}} is set.
Example configuration:
{noformat}
<build>
<plugins>
<plugin>
<artifactId>maven-dependency-plugin</artifactId>
<version>2.1</version>
<executions>
<execution>
<id>copy-snapshot</id>
<phase>compile</phase>
<goals>
<goal>copy</goal>
</goals>
<configuration>
<artifactItems>
<artifactItem>
<groupId>example-group</groupId>
<artifactId>example-artifact</artifactId>
<version>0.1.0-SNAPSHOT</version>
<overWrite>true</overWrite>
</artifactItem>
</artifactItems>
<stripVersion>true</stripVersion>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
{noformat}
Btw. {{copy-dependencies}} seems to honour the {{-U}} option, but
{{copy-dependencies}} may not be appropriate for all people's use cases.
