[ImageJ-devel] Maven problem

[Tobias Pietzsch]

Hi Steffi,

Projector2D has been replaced by IterableIntervalProjector2D recently in imglib2 core.
Apparently the version of imglib2 core you have is more recent than 2.0.0-beta-25, because that one doesn't have this change yet.
However, your imglib-ij project probably is build against the beta-25 and thinks Projector2D is still there.
(I'm really not looking forward to the world of split imglib repositories, I fear we'll see a lot of problems like this…)


Instead of overriding individually the version of imglib2, I would recommend just setting the version property in your pom to

	<properties>
		<imglib2.version>2.0.0-SNAPSHOT</imglib2.version>
	</properties>

Then in the actual dependencies don't give any version:

		<dependency>
			<groupId>net.imglib2</groupId>
			<artifactId>imglib2</artifactId>
		</dependency>
		<dependency>
			<groupId>net.imglib2</groupId>
			<artifactId>imglib2-realtransform</artifactId>
		</dependency>

and it should pick the managed one which is now 2.0.0-SNAPSHOT.

Could you try this?

best regards,
Tobias
