Grails - maven building war with version number - grails

Question

I am developing grails app using maven.
While running command "mvn package" it generates the war with version no. But I want to generate war without version no and also want to exclude some jars. Here is my pom.xml
<?xml version="1.0" encoding="utf-8"?>

mvn package generates the war my-grails-demo-1.0.war. I need to generate without version and also want to excludes servlet.jar

Answer 1

You can do either of these:
If you use mvn package then set the below setting in Config.groovy
grails.project.war.file = "target/${yourDesiredName}.war"
You can also package using mvn grails:war yourWarName.war
In order to excludes jar in wars, use below in BuildConfig.groovy:
grails.war.resources = { stagingDir ->
delete(file:"${stagingDir}/WEB-INF/lib/servlet.jar")
}
Piece of Advice:- Use mvn install instead of mvn package

Answer 2

You should be able to exclude jars that are transitive dependency with the provided scope in your dependency.
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>3.0</version>
<scope>provided</scope>
</dependency>
But to explicitly exclude a jar in the war plugin, you can use packagingExcludes, which it looks like you have. Is it possible there's a problem with the regex, have you tried simplying passing packagingExcludes a comma list of jars.
As for version number (which is required), you can change the name of generated war like with the finalName property within the build section
<build>
...
<finalName>your final war name</finalName>

Answer 3

I am making following entry in BuildConfig.groovy file to remove jar from lib folder.
grails.war.resources = { stagingDir ->
new File("${stagingDir}/WEB-INF/lib").eachFileMatch(~/.*(servlet).*.jar/) {
f -> f.delete()
}
}
I have to use regex because there are different versions of servlet.jar appearing in lib folder.
