使用Gradle脚本从Java文件创建WAR

Question

My directory sturcture is,
C:\\Grapher\\src\\ *.java
C:\\Grapher\\lib\\ *.jar

There are many java files and many jar dependencies. I want to create a tomcat deployable WAR.
Can any one suggest me how to create a WAR using a gradle script? What are the dependencies to be included in Gradle to create a WAR.

Answer 1

Have you read and understood https://docs.gradle.org/current/userguide/war_plugin.html ?

The War plugin adds two dependency configurations named providedCompile and providedRuntime. Those two configurations have the same scope as the respective compile and runtime configurations, except that they are not added to the WAR archive. It is important to note that those provided configurations work transitively. Let's say you add commons-httpclient:commons-httpclient:3.0 to any of the provided configurations. This dependency has a dependency on commons-codec. Because this is a “provided” configuration, this means that neither of these dependencies will be added to your WAR, even if the commons-codec library is an explicit dependency of your compile configuration. If you don't want this transitive behavior, simply declare your provided dependencies like commons-httpclient:commons-httpclient:3.0@jar.

If you use providedCompile or providedRuntime, those dependencies will not be added to your war archive.

The folder structure you need to have in your project is:

app
 |-src
    |-main
       |-java
       |-webapp

In the java folder you add your own packages and classes. In the webapp folder you add web content if your application makes use of such items.
