Grails - maven building war with version number

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 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 2

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 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.
