Filtering resources
Hi!
I need to be able to filter files where the values to replace are defind as
@aPlaceHolderThatNeedToBeSubstituted@
Does anyone know of a good, working example where a custom resource
filter is implemented?
I had a look at
http://maven.apache.org/plugins/maven-resources-plugin/examples/custom-resource-filters.html
and it is a bit sketchy. A complete, annotated example would be nice
where all details needed to implement this interface
MavenResourcesFiltering are shared.
A Git repo to clone would be the most awesome tip I can think of.
Cheers,
Thomas

This is obviously a complicated example if you allow empty tokens when
using the same delimiter as start and end indicator.
I don't think empty tokes are reasonable. I can't come up with sample
code that would do any reasonable filtering with
@@
Specifying this token in a property file would look like this:
= the actual value
So, to me empty tokens are an error or an indication of something else.
Empty tokens when using different delimiters such as ${} is possible
to detect since there are different start and end indicators. But the
question on what you should replace them with is still valid.

I would go with the latter. Which is consistent with how filtering in
Maven is implemented today.
This limits the possibilities a bit on where you can place nested
tokens. Using the same delimiter, you would only be able to place them
at the beginning or end. That is relying two or more of them next to
each other.
Given this, then would the example
@foo@bar@@
be equal to
${foo${bar}}
And
@@foo@bar@
be equal to
${${foo}bar}
Using the same delimiter to indicate start and end of a token is
complicated and it would have been nice if it wasn't allowed. But it
is. And heavily used in the filtering case I need to resolve.

I don't really see that it would be extremely complicated. Definitely
complicated using the same delimiter, but not impossible. Using
different delimiters for start and stop would make it easier.
Remembering Scheme, a lisp dialect, makes me wish for parentheses as
delimiters.
It actually surprises me that nested tokens isn't properly supported
in the case ${${foo}bar} or ${foo${bar}}
But it isn't when I am testing with Maven 3.3.9 and maven-filtering 3.0.0.

Thomas

Re: Filtering resources
Posted by Stephen Connolly <st...@gmail.com>.
and how do I differentiate @foo@bar@@ whether that would be equivalent to
either:
${foo}bar${}
or
${foo${bar}}
if using ${ } style delimiters for the start and end?
At least with ${ } style delimiters one can count braces...
how about @foo@bar@manchu@ is that supposed to be ${foo${bar}manchu} or
${foo}bar${manchu}
Start trying to answer that question and you will see that the rules get
very fast very quickly

As long as the delimiters are matched, I would expect a recursive
resolution of them.
That is,
@foo@bar@@
would first resolve the smallest part, @bar@ to something. Say 'ResolvedBar'.
Then it should resolve the larger part @fooResolvedBar@ to whatever
'fooResolvedBar' should be resolved to.
That is the behaviour that I would like to see. And the behaviour I
interpret the closed bug is refering to.
https://issues.apache.org/jira/browse/MRESOURCES-70
Just doing a token replacement token by token is easy to implement. A
recursive resolution is more complicated to implement.

Re: Filtering resources
Posted by Robert Scholte <rf...@apache.org>.
Hi,
What would you expect when start and end delimiters are the same in
combination with nested expression. Don't think that'll ever work.
I assume that in your case @PoolSize.@ and @@ are evaluated.
AFAIK only with different delimiters nested expressions could work.
thanks,
Robert

Re: Filtering resources
Posted by Thomas Sundberg <ts...@kth.se>.
Hi!
Filtering resources that uses @ as delimiters works.
This example works as expected:
@Environment@
But my use case involves filtering nested resources. An example looks like this:
@PoolSize.@Environment@@
There seem to exist a closed bug regarding nested variables.
https://issues.apache.org/jira/browse/MRESOURCES-70
Does anybody have another suggestion or should I implement my own
filtering as a custom resource filter?

You could also look at DefaultMavenResourcesFiltering
<http://maven.apache.org/shared/maven-filtering/apidocs/org/apache/maven/shared/filtering/DefaultMavenResourcesFiltering.html>
for
an example. I think this is still using plexus so you'll have to have the
component.xml iirc that is needed for components.

Re: Filtering resources

In general, though it would surely work too, better avoid using
maven-antrun-plugin.
Maven is about standardizing your build process, using antrun is gonna add
issues with IDEs and so on.
Anyway, what you ask for doesn't seem to me to require custom filtering.
'@' is a standard delimiter (see
http://maven.apache.org/plugins/maven-resources-plugin/resources-mojo.html#delimiters),
so it should work out of the box.
Just enable filtering on the resources folders you want and you should be
done.
Cheers

If you just want to get it done, use the maven-antrun-plugin with Ant
filtersets.
