Maven maven-assembly-plugin build with profile

Question

I am trying to use maven-assembly-plugin to build a lite and fat web application, the application will have different content later. I thought that I actually can use two profiles mvn -Pliteweb,fatweb package so it will create two build assembly for each profile. But when I run it, it actually only create one assembly that is in the bottom position in the pom ( the liteweb )

I already tried when I build it one by one its okay. I also check with mvn help:active-profiles -P fatweb,liteweb and it correctly show 2 active profile.

Below is my test pom ( its not including the difference in here, I just want it to create 2 War files and other assembly files separately ). I am still new at Maven so I might misunderstood this. Is creating multiple assembly from multiple profiles is possible to do?

fatassembly.xml for now I didnt put anything just to make sure everything work.

<assembly xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        </dependencySet>

</assembly>

liteassembly.xml same I didnt put anything to make sure everything work, but I already test with different thing inside still doesnt work.

</assembly>

When EXECUTING mvn help:active-profiles -Pfatweb,liteweb

Active Profiles for Project 'com.test.web:TEST_WEB:war:0.0.1':

The following profiles are active:

 - fatweb (source: com.test.web:TEST_WEB:0.0.1)
 - liteweb (source: com.test.web:TEST_WEB:0.0.1)

And below is what happen when I execute mvn -Pfatweb,liteweb clean package seems like it building the same zip twice.. From same xml assembly, but actually from different execution ( exec1 and exec2 )

So the profile actually active, but after that the one that build in target folder is only the LITEWEB. If anyone know, please help me to understand why it not create both and why mvn like build the zip twice. I know the workaround is just shellscript code to build twice (if I build one profile each time it work correctly), but I want to use only mvn specific build.

Below is what happen if I do mvn -Pfatweb,liteweb clean install the lib were created twice, but it only build the WAR file once. From the log I actually realized the one that build the WAR is the war-plugin, but how do I make it execute for both profile..?

Answer 1

In your POM move your <configuration> section FROM being under <plugin> TO being under <execution>. Do this for both <configuration> sections.

The error is that you configured the plugin 2 times. When both profiles are active, maven merges the 2 configurations, loosing one.
