How to get bootstrap classloader
by Kabir Khan
I need to generate a proxy for java.util.ArrayList using the same
classloader that java.util.ArrayList uses. The problem is that:
ArrayList.class.getClassLoader() == null
since it is the bootstrap classloader. I can think of a few ways to get
hold of the actual loader, but wondered if somebody knows an
elegant/obvious way to get hold of the clasloader?

MappedReferenceMetaDataResolverDeployer, client container updates
by Scott Stark
I'm in the process of committing the client container work and switch to
the MappedReferenceMetaDataResolverDeployer as the default resolving
deployer right now to validate the tck runs can get past the client
container issue. I expect some resource ref regressions as I work on
getting ejb3/ejb2 containers to declare proper supply/demands for ejbs.
If there is a particular regression affecting your tests let me know and
I'll try to fix it.

Maven weirdness: cannot find maven-dependency-plugin
by Kabir Khan
I've tried deleting my local
org/apache/maven/plugins/maven-dependency-plugin folder, and cannot get
a new version of the plugin. Following the mvn clean install shown
below, it only fetches down the metadata.xml files, and not the plugin
itself?

Why Maven sucks (part 1)
by Carlo de Wolf
This is going to be a long post, so grab a cup of coffee.
Let me start with the fact that I'm biased against Maven and before any
Maven hater starts cheering, don't. I still think we should use Maven to
it's full advantage (whatever that may be).
I don't think calling Maven an abomination and a piece of crap is not a
valid reason to ditch it. We need to form a well informed opinion on it.
Let's start with the goal of Maven and how we apply it.
"Maven is a software project management and …
[View More]comprehension tool. [...]
Maven can manage a project's build, reporting and documentation from a
central piece of information."
Our application of Maven is just to use it for dependency management. So
the complete Maven scope extends well beyond our requirements. This is
all fine if the requirement is properly met and if the tool limits
itself to that scope.
Problem 1 then appears: Maven is 'opinionated software'. In other words
convention is prioritized over configuration. Given that Maven goes
beyond scope and thus start mandating certain conventions outside the
'dependency management' area it starts to suck. I want be in control of
the build process and Maven to do dependencies. (We've attained that
goal in AS build, so we're stopping there.) But now we get a declarative
build process in which I have to describe my project and press a 'I'm
Feeling Lucky' button to see the result.
On to the second problem: the implementation of dependency management in
Maven. It looks fine on paper, but again it has a notion of being
'opinionated' and thus you're not in control. The version of
dependencies you specify in the pom.xml are advisements (WTF!). In
actuality Maven picks a semi random (okay I'm exaggerating a bit)
version instead of informing you that you're an idiot for mixing bad
stuff. Version ranges might help in this area by being more than just
advisements.
Now if it was a tool focussed on dependency management (like Ivy) it
would have solved the real problem: snapshots. So let's do an example:
- as trunk -> ejb3-core-0.1-SNAPSHOT ->
ejb3-interceptors-0.13-0-SNAPSHOT -> aop-2.1-SNAPSHOT (for the example)
If I happen to deploy a new snapshot of aop, it'll break AS build. Why:
ejb3-core is not compatible and Maven blindly loads it up. This is not
possible in Ivy, it's snapshot repository looks like:
- as trunk -> ejb3-core-0.1-20080421 ->
ejb3-interceptors-0.13.0-20080421 -> aop-2.1-20080420.
If I happen to deploy a new snapshot of aop you get and I run a nightly
build on ejb3 you get:
- as trunk -> ejb3-core-0.1-20080421 ->
ejb3-interceptors-0.13.0-20080421 -> aop-2.1-20080420
- ejb3-interceptors-0.13-0-20080422 -> aop-2.1-20080422
Since ejb3-core didn't properly build there is no new snapshot for it
and AS build is unaffected.
Combine this with unit tests and you got a pretty stable setup.
So at the end of the day we're not yet there with Maven:
1. It has crummy implementation of snapshots that needs to be fixed;
2. It must have proper conflict resolution;
So let's first make JBoss a shining example of how to do a mega project
with Maven. After that we can really do a well informed 'Why Maven sucks
(part 2)'.
