-------------------------------------
Summary: Dependency "force" does not work if comes from extended
module
Key: IVY-1422
URL: https://issues.apache.org/jira/browse/IVY-1422
Project: Ivy
Issue Type: Bug
Components: Core
Affects Versions: 2.3.0
Reporter: Vitaliy Sapounov
***** ENVIRONMENT:
We have a project that uses several Ivy modules:
1) There is a base module that declares dependency on "vendorlib", revision
1.0, with "force" attribute (the whole purpose of the module is to guarantee
the "vendorlib" revision):
<ivy-module>
<info organisation="com.mycompany" module="base" revision="trunk"/>
<dependencies>
<dependency org="com.vendor" name="vendorlib" rev="1.0" force="true"/>
</dependencies>
</ivy-module>
2) There is an extending module that extends the base and includes our library
"mylib":
<ivy-module>
<info organisation="com.mycompany" module="extending" revision="trunk">
<extends organisation="com.test" module="base" revision="trunk"/>
</info>
<dependencies>
<dependency org="com.mycompany" name="mylib" rev="trunk"/>
</dependencies>
</ivy-module>
3) Finally, our library "mylib" also depends on "vendorlib", revision 2.0 (i.e.
there is another dependency on "vendorlib" with revision 2.0):
<ivy-module>
<info organisation="com.mycompany" module="mylib" revision="trunk"/>
<dependencies>
<dependency org="com.vendor" name="vendorlib" rev="2.0"/>
</dependencies>
</ivy-module>
4) We use "latest-revision" conflict manager in ivysettings.xml.
***** PROBLEM:
Despite the "force" attribute in base module for "vendorlib", latest revision
(2.0) of "vendorlib" is selected by the conflict manager for the extended
module.
***** ROOT CAUSE:
LatestConflictManager.java has the following code:
public Collection resolveConflicts(IvyNode parent, Collection conflicts) {
if (conflicts.size() < 2) {
return conflicts;
}
for (Iterator iter = conflicts.iterator(); iter.hasNext();) {
IvyNode node = (IvyNode) iter.next();
DependencyDescriptor dd = node.getDependencyDescriptor(parent);
if (dd != null && dd.isForce()
>>>>>>>>> &&
>>>>>>>>> parent.getResolvedId().equals(dd.getParentRevisionId())) {
return Collections.singleton(node);
}
}
Note ">>>>" line: since "vendorlib" with "force" attribute comes from the base
module, dd.getParentRevisionId() returns "com.mycompany#base;trunk", but
parent.getResolvedId() returns "com.mycompany#extended;trunk", thus the last
comparison returns "false" and "force" is lost.
If we move dependency with "force" to the extended module, it will work.
***** REAL-LIFE APPLICABILITY:
We use the "base" module as a template that fixes versions of libraries
provided by the J2EE application server we use. Based on that template, we
create a number of extending web applications that guarantee to use the libs
that the application server provides. (The actual use case is slightly more
complicated, as e.g. "mylib" declares dependency on "vendorlib" version range
it supports, e.g. "[2.0,5.7]" range.)
