Re: Maven 4.0.0 Release - Thoughts?

[Guillaume Nodet]

Hi all,

I have several significant features waiting as PRs (mixins and
cascading profiles), but I’ve decided to postpone them until 4.1.0.
For what it’s worth, several people, including the IntelliJ team, have
expressed concerns about 4.0.0 being a moving target due to the
continuous addition of new features in RCs.

I’d prefer to release 4.0.0 with a limited set of new features to
ensure stability and reserve the larger changes for 4.1.0, which we
could target for the end of year.  This could also include the upgrade
to JDK 21 since JDK 25 should be released in September.

What are your thoughts on this approach?

Best,
Guillaume Nodet

As much as I keen on mixins as I won’t be able to actually use 4.0.0, I’d
down for seeing 4 get out sooner rather than later. If that helps Jetbrains
and other IDE tool vendors a stable version to work with, that’ll help with
wider adoption and upgrades.

I suspect there might be a need for a 4.0.1 etc. once it hits the wider
world as well - or more than likely, a raft of third-party plugin updates.

Re: Maven 4.0.0 Release - Thoughts?

[Matthias Bünger]

Hey,
I‘ve lost the overview to the java 24 issues, but if I got it right the sisu 
0.94 can handle it. So if we are fine on running on java 24 and our 4.x plugins 
(there are  some in beta etc, look at the update parent to 44 of source-p for 
example) are final too, I think we are good to go. 
Why the plugins? Think it’s not good to say „here main is final, use the 4.x 
plugins of those exist, bit yes they are alpha/beta“. 

Another point we can consider: finish enable github issues for all relevant 
projects to make it easier and consisten for users to provide feedback/issues. 
Slawek and I are close to finish. If I have it in mind correctly about 15 repos 
left, including maven itself (long standing draft afair). 

Have a good night everyone. 
Matthias

Big +1 to that. The maven 4 cycle has stretched for a long time and having
an actual release which can be targeted by the tool vendors would be a
great thing.

Re: [HEADS UP] Maven 3.9.10 release

[Sergey Chernov]

It would be great to have 3.9.10-rc-1 available at 
https://repo.maven.apache.org/maven2/org/apache/maven/apache-maven/ similar to 
what is available for 4.0.0 versions. WDYT?
It’s much easier to use such dist instead of building own.

That I’m not sure - since we can’t run our builds under Maven 4 (tiles,
mixins, the problems of my ownn makings) I’ve not really tried M4 outside
of small projects.

I should check the OSGi bundle-maven-plugin along with the ANTLR plugins we
use.

I don't get what plugin updates are expected: are there Maven 3 plugins known 
to fail on Maven 4? If yes, are they so many?

I hope releasing Maven 4 will help clarify
which plugins will continue to be maintained as Maven 3 plugins "just working 
on Maven 4"
and which plugins will absolutely require to fork a Maven 4 branch from usual 
Maven 3 one because it's not possible to keep it simple...

Hervé

Re: Proposal: Reactivating PMD to Strengthen Definition of Done

[Martin Desruisseaux]

I agree with Elliotte and his example with parenthesis. I do not 
consider "unnecessary parenthesis" as a violation, since they sometime 
improve code readability. The last time that I used PMD in a big project 
(years ago), we had thousands of warnings reported as "violations" that 
we considered as false positives. We abandoned the use of PMD because 
the filtering of the false positives was too much effort. We could have 
keep PMD for a few major rules for which violations are almost always 
real errors, but those PMD rules are not so numerous and many of them 
are already covered by javac warnings.


It does not mean that PMD is bad. I have nothing against PMD if someone 
is willing to maintain its use. But I suspect that the 500 PMD 
violations may include a lot of false positives, so fixing all 
violations should not necessarily be a goal.

Maybe. Maybe not. I don't think most of these can be simply assumed to
be correct. For instance "Unnecessary parentheses" can nonetheless be
extremely helpful in clarifying code. Removing them is in no way a
best practice. Sometimes it's a good idea. Sometimes it's actively
harmful. The same is true for a lot of other static analysis rules.
Human attention is necessary.

On Mon, May 19, 2025 at 7:37 AM Vincent Potucek  wrote:

Hi Devs,

hope you doing well.

We’re currently facing real production bugs, along with approximately 500 PMD 
and 300 SpotBugs violations. This clearly exposes a gap in our current 
Definition of Done, especially regarding best practices and principles like 
convention over configuration, maintaining code quality, and aligning with 
industry standards.

It’s the past calling—demanding attention and refusing to be ignored until 
properly addressed.

While static code analysis isn’t new to us—we already use Checkstyle and 
Spotless—these tools alone don’t cover the full range of potential issues. Each 
having its own strength, chaining them together ensures broader, more effective 
coverage.

To that end, the current PoC reintroduces PMD to help enforce Java best 
practices. By suppressing the existing 483 PMD violations, this change enables 
us to merge the configuration without blocking ongoing development—while still 
preventing new violations from being introduced:

🔗 Enable PMD with suppressed existing violations 

The following PRs address individual violations—most of which can be easily 
fixed with IDE support:

🔗 PR 2350: UnusedAssignment 
🔗 PR 2349: UnnecessaryParentheses 
🔗 PR 2348: UnnecessaryFullyQualifiedName 

We increase both quantity and quality by locking in the current state and 
enforcing stricter standards moving forward. This allows us to stop regressions 
now and tackle legacy issues incrementally after integration.

Please don’t think of best practices as vague recommendations—they are settled 
standards embraced by a wide community. The real question is: do we want to 
align with common code quality standards and industry norms?

Exceptions will be allowed using suppressions whenever justified.
