Gradle -> How to omit some jars from WEB-INF/lib
apache-tomee, gradle, jar, java, war
Solution
the obvious way to go is to move the dependencies you don't want to have in your war from the `compile` configuration to `providedCompile` and from `runtime` to `providedRuntime`. the provided configurations are added to your build when the war plugin is applied.
One other note on your snippet above: I think the exclude does not work because you referencing the target path in your exclude statements instead you should just reference it by `/servlet-api-2.5.jar`.
Problem
I have a subproject with a war spec that looks like this: ``` war { from('resources') { include '*.properties' into 'WEB-INF/classes/' } webXml = file('src/main/webapp/WEB-INF/web.xml') } ``` Works great. Creates a single, fat war file that is deployable to Tomcat. Problem is, when deploying to TomEE and JBoss, I run into conflicts (ie with Javax Servlet, Jersey, etc). So I want to exclude a set of jars from being war'd. I looked at the Gradle war documentation, and it looks like I need to use excludes for this. I tried it two different ways, and the jars are not excluded from the war: ``` war { // copy properties file in classes so that // they may be loaded from classpath from('resources') { include '*.properties' into 'WEB-INF/classes/' } // specify web xml webXml = file('src/main/webapp/WEB-INF/web.xml') // remove jars that conflict with TomEE exclude '**/javax.inject-1.jar' exclude '**/javax.servlet-2.5.0.v201103041518.jar' exclude '**/servlet-api-2.5.jar' exclude '**/validation-api-1.0.0.GA.jar' } ``` This is in a subproject (karyon-examples) within the NetFlix/karyon project hosted on github. The dependencies in the subproject look like this: ``` dependencies { compile 'org.slf4j:slf4j-api:1.7.0' runtime 'org.slf4j:slf4j-simple:1.7.0' compile project(':karyon-extensions') compile project(':karyon-admin-web') } ``` And I want to avoid editing things like compile versus runtime dependencies, especially in other files and subprojects. In fact the jars I am trying to exclude above are benign when running with jetty and regular tomcat. I simply want to exclude these jars without complicating the build scripts. What am I missing?
