Configurations collect including multiple verions

Help/Discuss

Hi,
I am building an RPM from a gradle project using gradle ospackage plugin.
So The RPM is to include a lib folder with all the compile dependencies of the project, simple enough.
I have:

from (configurations.compile.collect()) {
    into 'lib'
}

This puts a bunch of dependencies into the ‘lib’ folder in the RPM root but it includes multiple versions of some of the packages. For example, a

rpm -qlp build/distributions/my.rpm

can produce

....
/path/to/rpm/lib/log4j-1.2.15.jar
/path/to/rpm/lib/log4j-1.2.16.jar
/path/to/rpm/lib/log4j-1.2.17.jar
....

How can I make it only include the one version of log4j and all other duplicated dependencies?

So I am a complete fool.
I forgot that I had overridden some of the dependencies with file dependencies, hence the different versions.
Sorry :frowning:

Something else to watch out for is that calling collect() on the configuration will cause the configuration to be resolved during Gradle’s configuration/evaluation phase. This is something that should be avoided as a general best practice.

You can use the configuration directly when calling from() and the configuration will only be resolved if the task is actually executed.

I actually had an issue whereby a dependency resolve (really a dependency substitution) wasn’t being included in a detached configuration. I therefor had to switch it to a:

 compile(......){
       exclude group: ....
 }
 compile "....."

Would using “from” solve this issue?

I was trying to execute the ‘jmh’ task of the gradle-jmh plugin.
Thanks anyways for the tip
