maven dependency and war file

[szms <sh...@hotmail.com>]

Hello...

I have two projects A and B

B depends on A.

If I make any changes on project A and run mvn install on project B, the
changes from project A does not get included to war file for project B.

However, if I run mvn install on project A and then run mvn install on
project B, the changes from project A gets included to war file for project
B.

Is this normal? Is there any way to get project B updated with project A
with running mvn install on project A?

I think you mean an aggregating project.

In this case I would stress that this is only appropriate if A and B
are related and it is appropriate to (always) build them together.

A different solution would be to use an IDE that will use workspace
resolution instead of repository resolution. It would then use the
current code base instead of what's in the repository. I know that
Eclipse with m2e supports this, but there might be others as well.
This would be my suggestion. IMHO, you don't want to have to do a
Maven build whenever you do a small code change but rather have that
happen in runtime (codetime?).

I am pretty new in Maven. Please bear with me.

How would pom and assembly file would look like on parent project?

Thank you.

Make a parent over A and B.
Build from the parent.
Set a dependency from B to A.
Changes in A will go into B.
