Matt Hurne created IVYDE-303:
--------------------------------
Summary: NullPointerExceptions possibly related to project
ivy.xml's use of <extends>
Key: IVYDE-303
URL: https://issues.apache.org/jira/browse/IVYDE-303
Project: IvyDE
Issue Type: Bug
Affects Versions: 2.2.0.beta1
Reporter: Matt Hurne
Priority: Critical
In both Eclipse 3.6 and 3.7, we are finding IvyDE 2.2.0.beta1 to be unusable
due to NullPointerExceptions occurring when we attempt most IvyDE operations.
For example, the following occurred after right-clicking on the project and
selecting Ivy > Resolve:
{noformat}
eclipse.buildId=M20120208-0800
java.version=1.6.0_21
java.vendor=Sun Microsystems Inc.
BootLoader constants: OS=win32, ARCH=x86, WS=win32, NL=en_US
Framework arguments: -product org.eclipse.epp.package.jee.product
Command-line arguments: -os win32 -ws win32 -arch x86 -product
org.eclipse.epp.package.jee.product
Error
Mon May 07 12:13:41 EDT 2012
An internal error occurred during: "IvyDE resolve".

We suspect this may be related to the project's ivy.xml's use of <extends>
since the stack trace above mentions the "module inheritance repository"
apparently added in Ivy 2.3.0-rc1. For example:
{noformat}
<?xml version="1.0" encoding="UTF-8"?>
<ivy-module version="2.2" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:noNamespaceSchemaLocation="http://ant.apache.org/ivy/schemas/ivy.xsd";>
<info organisation="foo" module="bar" revision="1.0.0" status="integration">
<extends organisation="foo" module="parent" revision="1.0.0"
extendType="all"/>
</info>
...
</ivy-module>
