I am trying to build a web application server using WildFly Swarm and the application has to be able to run another Java program inside (I don't want to run it as an external process). I am trying to include the external program as .jar dependency to my web application, however, wildfly-swarm-package task always fails with the following:
:clean
:compileJava
:processResources UP-TO-DATE
:classes
:war
:wildfly-swarm-package FAILED
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':wildfly-swarm-package'.
> java.lang.NullPointerException (no error message)
This is my gradle.build file:
buildscript {
version = System.getProperty('swarmVersion') ?: '2016.10.0'
repositories {
mavenLocal()
mavenCentral()
}
dependencies {
classpath "io.spring.gradle:dependency-management-plugin:0.5.6.RELEASE"
classpath "org.wildfly.swarm:wildfly-swarm-plugin:$version"
}
}
apply plugin: "io.spring.dependency-management"
apply plugin: 'wildfly-swarm'
apply plugin: 'java'
apply plugin: 'application'
apply plugin: 'war'
//mainClassName = 'org.siret.prank.webapp.rest.Main'
swarm {
properties {
swarm.http.port = 8181
}
}
repositories {

compile fileTree(dir: 'libs', include: ['*.jar'])
compile fileTree(dir: 'libs/lib', include: ['*.jar'])
}
task debugJar(dependsOn:"wildfly-swarm-package") << {
javaexec {
main="-jar";
args=[
"-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5006",
"build/libs/prank-webapp-swarm.jar"
]
}
}
task runJar(dependsOn:"wildfly-swarm-package") << {
javaexec {
main="-jar";
args=[
"build/libs/prank-webapp-swarm.jar"
]
}
}
War plugin works fine, I can find the jars in WEB-INF/lib directory in the archive.
As an experiment, I tried to empty the libs folder and the error still persists.
Thanks, Lukas
