Sergei Ivanov created MRRESOURCES-58:
----------------------------------------
Summary: 'process' goal fails with NPE at the root of a reactor if
child modules use version ranges for dependencies
Key: MRRESOURCES-58
URL: https://jira.codehaus.org/browse/MRRESOURCES-58
Project: Maven 2.x Remote Resources Plugin
Issue Type: Bug
Affects Versions: 1.2.1, 1.3
Environment: Apache Maven 3.0.3 (r1075438; 2011-02-28 17:31:09+0000)
Java version: 1.6.0_25, vendor: Sun Microsystems Inc.
Default locale: en_GB, platform encoding: UTF-8
OS name: "windows xp", version: "5.1", arch: "x86", family: "windows"
Reporter: Sergei Ivanov
Attachments: test-reactor-version-ranges.zip,
version-ranges-bugfix.patch
When the maven-remote-resources-plugin:process goal is integrated into the
lifecycle of a parent project in a multi-module reactor build, the goal fails
with an NPE if dependency version ranges are used in the child modules.
Additionally, "runOnlyAtExecutionRoot" option needs to be set to true in order
to recreate the problem. Please see the attached test project that demonstrates
the problem.
Full exception trace is as follows:
