using the fixed version the assembly plugin (and others

not what's in

As suggested I changed the dependency versions to
${project.version}, but it did not help. The

The use of an explicit version is the problem. Instead of
0.0.3-SNAPSHOT try depending on ${project.version}. In my experience
using the fixed version the assembly plugin (and others like the
dependency copy goals) will use what's in the local repo not what's in
the reactor.

I'm releasing a Maven2 multi-module project. One of the
modules is
a POM
project (assembly project) that uses the
maven-assembly-plugin
in
order
to
build an assembly (zip archive). The artifacts to be assembled
are specified via dependencies in the POM. They point
to modules
contained in the same multi-module project.
When running mvn release:prepare on the multi-module
project, the
build of the assembly project fails with the message that the
dependencies cannot be resolved. These dependencies are
reported with the version that should be released,
e.g. 0.0.3.
Before running the goal, all dependency versions are
0.0.3-SNAPSHOT.
What seems to happen is that the snapshot version
0.0.3-SNAPSHOT
is replaced by 0.0.3 and then the assembly plugin is started
(which is bound to the package phase).
what goal did you bind with?
It needs to be assembly:single
Yes, it is goalsingle/goal
The assembly plugin tries to resolve the dependencies based on
version
0.0.3 which however do not yet exist at that point.
The exist in the reactor, providing the project in which
assembly is
being
invoked has dependencies on those artifacts so that maven knows
the build order must build the dependent projects first.
to test if you have this working, here is a simple test
procedure:
1. mvn versions:set
-DnewVersion=0.0.3-reltesting-SNAPSHOT
2. mvn clean verify
3. mvn versions:rollback
3. mvn versions:revert
I executed this test procedure on the assembly project
and in fact
it produces the same problem as described above: the
artifacts to
be assembled are looked up in the repository with version
0.0.3-reltesting-SNAPSHOT and the build fails because the
artifacts have not yet been installed with this version.
For me it looks like a hen-and-egg problem: releasing
the assembly
project implies building the assembly in the release
version, but
the assembly in turn requires the released artifacts to be
installed in the repository.
Would it be possible to have the release procedure work
like this:
1) Release plugin changes the version in the multi
module project
(that includes the assembly project and the artifacts to be
assembled), i.e. to
0.0.4
2) The artifacts to be assembled are built and installed in the
repository in version 0.0.4
3) The assembly is run and picks up the artifacts to be
assembled
from the repository in version 0.0.4
4) The assembly project is installed in the repository
in version
0.0.4 Currently the install step in 2) is not happening -- this
seems to be the crucial part
If you bind things to the correct phases and have the correct
project
structure then there is no need to invoke the local
repository and
everything is resolved from the reactor.
You just need to restructure your project.
Where is the assembly created?
Where is that in relation to it's dependencies?
The project structure is currently as follows:
commons
|
|-- commons.util
|
|-- commons.util.test
|
|-- commons.distribution
| |
| |-- assembly_descriptor.xml
where commons.distribution is the assembly project.
Its pom.xml
configures the assembly plugin like this:
plugin
artifactIdmaven-assembly-plugin/artifactId
executions
execution
idmake-assembly/id
phasepackage/phase
^^^ good, if you use a phase prior to package it would fail
goals
goalsingle/goal
^^^ good that is the correct goal to call
/goals
/execution
/executions
configuration
descriptors
descriptorassembly_descriptor.xml/descriptor
/descriptors
finalNamecommons/finalName
/configuration
/plugin
The projects contained in the assembly are the two sibling
projects
commons.util and commons.util.test (both are Java projects
packaged as
jar).
They are included in the assembly descriptor via
dependencySets (I'm
not sure if moduleSets would be more appropriate in this
case)
are they also listed as dependecies of commons.distribution?
Yes, they are
