Re: ZooKeeper Roadmap - 3.1.0 and beyond.
Congrats on the release. Now that has been completed, I'd like to see
if you guys are willing to revisit the issue of a maven based build.
If yes, I'd be happy to assist making that happen.
Regards,
Hiram

Like I said, ant works fine. And yes you can hack up your ant build
to push bits to maven repos. But like I said before, there is lots
more to maven than just that.

Re: ZooKeeper Roadmap - 3.1.0 and beyond.
Posted by Robert Newson <ro...@gmail.com>.
Lucene's top-level build.xml has this;
<target name="generate-maven-artifacts"
depends="maven.ant.tasks-check, package, jar-src, jar-demo-src,
javadocs">
<sequential>
<m2-deploy pom.xml="lucene-parent-pom.xml.template"/>
<m2-deploy pom.xml="lucene-core-pom.xml.template">
<artifact-attachments>
<attach file="${build.dir}/${final.name}-src.jar"
classifier="sources"/>
<attach file="${build.dir}/${final.name}-javadoc.jar"
classifier="javadoc"/>
</artifact-attachments>
</m2-deploy>
<more follows>
</target>
lucene-core-pom.xml.template is this;
<project>
<parent>
<groupId>org.apache.lucene</groupId>
<artifactId>lucene-parent</artifactId>
<version>@version@</version>
</parent>
<modelVersion>4.0.0</modelVersion>
<groupId>org.apache.lucene</groupId>
<artifactId>lucene-core</artifactId>
<name>Lucene Core</name>
<version>@version@</version>
<description>Apache Lucene Java Core</description>
<packaging>jar</packaging>
</project>
The maven extension to Ant is pulled in with;
<project xmlns:artifact="antlib:org.apache.maven.artifact.ant">
availability is tested with;
<available
property="maven.ant.tasks.present"
classname="org.apache.maven.artifact.ant.Pom"
/>
and the entire m2-deploy macro is;
<macrodef name="m2-deploy" description="Builds a Maven artifact">
<element name="artifact-attachments" optional="yes"/>
<attribute name="pom.xml" default="${pom.xml}"/>
<sequential>
<copy file="@{pom.xml}" tofile="${build.dir}/@{pom.xml}">
<filterset begintoken="@" endtoken="@">
<filter token="version" value="${version}"/>
</filterset>
</copy>
<artifact:install-provider artifactId="wagon-ssh"
version="1.0-beta-2"/>
<artifact:pom id="maven.project" file="${build.dir}/@{pom.xml}" />
<artifact:deploy file="${build.dir}/${maven.project.build.finalName}.jar">
<artifact-attachments/>
<remoteRepository url="${m2.repository.url}">
<authentication username="${m2.repository.username}"
privateKey="${m2.repository.private.key}"/>
</remoteRepository>
<pom refid="maven.project"/>
</artifact:deploy>
</sequential>
</macrodef>
So, you can put Maven shaped artifacts side by side with build.xml and
generate the appropriate artifacts. After that, it's just a question
of getting upload permission to the main repository.

Any idea what it takes to do this? I noticed that Ivy just pushed a new
v2 release candidate to apache-announce, is that necessary (ivy) or will
straight ant work? From the ZK release management perspective how much
additional work is required?

Re: ZooKeeper Roadmap - 3.1.0 and beyond.
Posted by Robert Newson <ro...@gmail.com>.
The Zookeeper development team should use whatever build system works
for them, Ant is a good option (Ant+Ivy looks quite compelling,
though).
However, for those of us, myself included, that do use Maven, could
Maven artifacts be deployed to the main repository as part of the
release cycle? That is the binary jar, source jar and javadoc jar?
It's not necessary to use Maven to do so (though it is easier); the
Lucene team push releases and they 'still' use Ant.

There are ate least 4 Apache Top Level Projects that use maven for
releases. So you could copy any their release processes if that's is
holding you back.

As I stated earlier in this thread we're planning to stay with ant for
many reasons, but in particular; 1) current build process works, 2)
current build is based on how hadoop projects in general (core for
example) is currently doing builds. By using the same process/toolset we
have many benefits - in particular being able to essentially "clone" the
core release process, saving us much time/effort.

Re: ZooKeeper Roadmap - 3.1.0 and beyond.
Posted by Fernando Padilla <fe...@alum.mit.edu>.
I will summarize my vote by echoing what Jake said:
"So while I would say it is never a bad decision to move to maven, it
isn't always a needed decision."
Though Maven hasn't won over everyone yet builds, the idea of a central
Maven Repository for dependency distribution and management has proven
itself and is a very solid and very useful system. So in the end of
day, use Maven or Ant+Ivy, or whatever, but I vote that you have to
support the central Maven Repository appropriately.
So it sounds like we're in agreement ( at lease the few in this
discussion ). But have we heard from the actual developers? What are
their preferences or plans? Or would they like patches?

Re: ZooKeeper Roadmap - 3.1.0 and beyond.
Posted by Jake Thompson <ja...@jakethompson.com>.
Hi Hiram,
I actually am just a user of zookeeper, I am not a "member" as of yet. I am
also a user of maven and ant and have been using both for many years.
So while I would say it is never a bad decision to move to maven, it isn't
always a needed decision.
A standard build structure makes sense if you were building zookeeper
yourself, but I don't beleive you would be doing that. So that leaves the
creation and building of your own projects like an ear, war, JBI, etc. The
problem with zookeeper is that there is no required project structure.
There is no zar that is to say.
I personally have a mavenized war project that I am using zookeeper in and I
also have a hand rolled CL java program that uses it and is build with ant.
For both of these I just needed to copy one jar into my lib.
As far as dependency management, since zookeeper is so simple the only
requirement is log4j, not really needing any complex dependency tools there.
As far as modularity, again I see zookeeper being part of larger modules, so
I don't know if we can draw a common modular zookeeper application
structure.
Maven is a great tool and can help alot, but I personally don't see it as
synonymous with modern java development.

Re: ZooKeeper Roadmap - 3.1.0 and beyond.
Posted by Hiram Chirino <hi...@hiramchirino.com>.
It would help new developers work with your project. Maven provides a
a broad set of tools that lots of java developers have come to expect
out of a build system. Incorporating those tools manually into an Ant
based build would be very time consuming and make the build complex to
maintain.
For example, in addition the standard build and package aspects of
build, folks expect the build system to:
- support generating the IDE integration files (Idea, eclipse, etc.).
- Run static analysis tools like find bugs
- Run test coverage reports
- Deployment to central servers
- License Checking
- Artifact signing
And most importantly, they want a standard way of doing all that.
Maven also encourages modularity in the architecture by making it easy
build multiple modules/jar files and easily describing the
dependencies between then. And once you go modular, you will see how
folks start contributing alternative implementations of existing
modules. Copying a module and it's build setup is easy to do with
maven.. A bit harder with something like ant since it's kinda
monolithic.
Ant was a great tool so if you guys want to stick to your guns that's
cool. But in this day and age, using a ant based open source project
is kinda like it was when we used make several years back to build
java projects. Works fine, but dated.

Apache Ivy has also been looked at, I believe Hadoop Core is considering

If someone could deploy a build to a public maven repository it would
really help zk client development and adoption when integrating with
external maven-ized projects, since adding such a dependency is
trivial in maven.

Re: ZooKeeper Roadmap - 3.1.0 and beyond.
Posted by Patrick Hunt <ph...@apache.org>.
Hi Hiram, afaik there is currently no interest (esp. among the
contributors I've talked with) to switch from ant to maven. For the time
being we are sticking with whatever Hadoop Core uses wrt
build/release/etc... I know I've personally (in my role as release
manager) gained a lot of benefit by "cloning" the Core process, scripts,
documentation, etc...
Regards,
Patrick
