Tomcat无法启动Gradle Webapp

Question

I have a Gradle webapp having plugin war and jetty defined in build.gradle , as follows:

apply plugin: 'java'
apply plugin: 'war'
apply plugin: 'jetty'

group = 'com.company'
sourceCompatibility = 1.8
targetCompatibility = 1.8
version = '1.0'
war.baseName = 'deploy'

repositories {
    mavenLocal()
    mavenCentral()
    maven { url "http://repository.pentaho.org/artifactory/repo/" }
}
dependencies {
    ..
}

When I perform a gradle build with jettyRunWar , as follows:

$ ./gradlew jettyRunWar

It build the application and deploy it to Jetty as expected.

Now I want to deploy the same application to Tomcat7 as well, to do the same, I ran the gradle war task as follows:

$ ./gradlew war

after running the task, I can see the deploy-1.0.war inside /Users/ArpitAggarwal/deploy/build/libs/ and when I tried to deploy it to Tomcat7, it's not picked up by Tomcat.

My question is - Do I need to apply any additional plugin to make the application deployable to Tomcat7?

Thanks.

Answer 1

war plug-in only creates a war, it doesn't deploy generated war to tomcat by itself.

You can create a task to deploy war to tomcat.

task deployToTomcat(type: Copy) {
    from war.archivePath
    into "${tomcatHome}/webapps"
}

You can also use gradle-tomcat-plugin .

Answer 2

The problem is contextRoot of .war file. Gradle generates the contextRoot of .war file picking the war.baseName and version , so the contextRoot is changed to deploy-1.0 and the application is accessible at:

localhost:8080/deploy-1.0

Then I removed the version field from build.gradle which makes Gradle generate .war with contextRoot as deploy and application accessibility at:

localhost:8080/deploy/
