[proposal] java5 as minimal runtime for maven 2.1 (and 2.0.10 ?)
Hello,
As you can read at http://java.sun.com/j2se/1.4.2/
*" J2SE 1.4.2 is in its Java Technology End of Life (EOL) transition period*.
The EOL transition period began Dec, 11 2006 and will complete October 30th,
2008"
I don't think we have plan yet to release maven 2.1, so I think it would be
a valid to require java 1.5 as minimal runtime.
Main beneficts (IMHO) :
- annotation can replace javadoc-style IoC an Maven plugin declarations
(code allready available :
http://docs.codehaus.org/display/MAVEN/Java+5+Annotations+for+Plugins)
- jsr-250 annotations can replace some plexus interfaces ( LogEnabled ->
@Resource('log') , Initializable --> @PostConstruct ...) and make component
more "standard" and accessible to developpers without plexus knowledge.
- generics can make the maven model more comprehensible. The current
"Collection project.getArtifacts()" is not really clear and the fiew
available javadoc don't help a lot.
Other possible improvements :
- plugin test tool could use jUnit 4 runners to create something comparable
to spring-test-context :
annotate your plugin test class with @Runwith( "MavenPluginTestRunner" )
@Pom( "myTestPom.xml" )
and the test will prepare the plugin set in the test pom and inject it in
the test class.
- benefict from java.util.concurrent to do some tasks in parallel ? Example
: dependencies downloading
- any other ?
WDYT ?
Nicolas.

Right, I missed this thread. I don't understand the Eclipse limitation about
required JRE but can believe there is some impacts. As the same "EOL"
applies to eclipse, and many eclipse plugin require java5, could we ignore
this platform limitation few users will not survive when maven 2.1 will be
released ?

We did it here a long time ago, but we asked Eclipse users because
they are more effected by limitations of the platform. Go look in the
mailing archive, there was a long discussion on this list. In short
the impact to users of IDEs, especially Eclipse, has far more impact
then general command line usage. From what's been seen so far almost
everyone could survive on the CLI with 1.5, but when things in Eclipse/
WTP integration not working on older versions of the target platform
is a real nightmare so that's why we asked there, in addition to here.

Why did this happen on m2eclipse-users list and not on maven-dev one ?
If one dependendency now requires Java5,why still retrotranslate others ?

Yes.
Two dependencies, maven-artifact and XBR, now use Java 1.5. Look in
the POM for maven-artifact and if you run the build for trunk you will
see the retrotranslation artifacts.
I retrotranslated maven-artifact so that users of 1.4 in m2eclipse
would not be inconvenienced. I have not retrotranslated XBR as we
asked users about 1.5 use on the m2eclipse list and the only people
that responded were those who wanted to drop support for 1.4. Users
don't seem to be bothered about dropping 1.4 so at least in trunk I
don't think we're going to harm anyone going to 1.5. I would very much
rather use 1.5, I just don't want to inconvenience or screw users
inadvertently.
We cannot require 1.5 in the lifetime of the 2.0.x series, as we just
don't know what people are using and how.

Right about leaving 2.0.10 as is, and use it for maintenance purpose only.
About 2.1 beeing already java 1.5, I can read this in main POM.xml :
<artifactId>maven-compiler-plugin</artifactId>
<!-- Maybe someday...
<configuration>
<source>1.5</source>
<target>1.5</target>
</configuration>
-->

This is already the case for 2.1, and we can't change it in 2.0.10. Just
because we used to break peoples' builds with regularity doesn't mean it

I don't see getting a tremendous amount of benefit from switching
2.0.10 (or whatever you want to call it) to require 1.5 without in
turn making however benign changes to the codebase...which would not
be fixing issues directly and potentially expressing new ones which
largely takes it out of the realm of a maintenance release imo.
I am perfectly fine with 2.1 requiring 1.5 but I think 2.0.x ought to
stick with the minimal requirements it is sitting at already

That could be an option to keep in mind when/if we define a roadmap for 2.1
release.
If a 2.1 release can't be expected soon (i.e some mounth) we could rename it
2.2 and prepare a 2.1 release to be feature equivalent to 2.0.x but require
java5.
That beeing said, changing requirements for a "maintenance" release is not
IMHO a blocker. Many 2.0.x upgrades required some fixes to existing
projects, as detailled in release notes. I think the only reason for a minor
version is when some features gets removed... just my 2cents.

Perhaps 2.1 needs to be changed to 2.2 and then 2.1 can be used for
what would be 2.0.10 + Java5

+1 - doing the same here.
And as it was mentioned earlier 1.4 is EOL. Let's move on and get the goodies :-)

This is allready not a limitation : I'm building java 1.3 projects using
maven 2 running on JDK 6. I simply use the compiler target=13 and
bootclasspath to point to JRE1.3 rt.jar. The toolchain would make this even
simplier as the JRE1.3 path has to be set by developers in settings.xml
using a non-standard property.

+1 for Maven 2.1, -1 for Maven 2.0.10 (doesn't feel right to bump minimum
requirements in a maintenance branch).
Once we have the toolchains fully in place and allow easy cross-compiling
independently of the JDK running Maven, there seems to be no reason why the
build tool shouldn't be run with a higher Java than the minimum JRE for the
project under build.

In particular, strongly typed collections will not only help developers to
understand the intended contents but enables the compiler to actually
enforce it.

Yah, I think that will be the consensus. I don't really want to find
out we've jacked up someone's environment by forcing 1.5. Brian did a
really awesome job that last release killing many regressions and I'd
like to keep it that way.

My only concern would be plugins... but since 2.0.9 locked down the plugin
versions that should not be as big an issue any more

I think the sentiment is fairly clear. I am going to unwind the
retrotranslating I put in place and leave 2.1 requiring Java 1.5.
