gradle - Wildfly Swarm部署问题-无法解决工件 'xalan:serializer:2.7.1.jbossorg-2'

Question

使用gradle脚本:

buildscript {
    version = System.getProperty('swarmVersion') ?: '2017.1.1'

    repositories {
        mavenLocal()
        mavenCentral()
    }

    dependencies {
        classpath "io.spring.gradle:dependency-management-plugin:1.0.0.RC2"
        classpath "org.wildfly.swarm:wildfly-swarm-plugin:$version"
    }
}

apply plugin: "io.spring.dependency-management"
apply plugin: 'wildfly-swarm'
apply plugin: 'java'
apply plugin: 'application'

mainClassName = 'test.Main'

swarm {
    properties {
        swarm.http.port = 8080
    }
}

repositories {
    mavenLocal()
    mavenCentral()
    maven {
        url 'https://maven.repository.redhat.com/nexus/content/repositories/releases/'
    }
    maven {
        url 'https://maven.repository.redhat.com/nexus/content/repositories/thirdparty-releases/'
    }
}

dependencyManagement {
    imports {
        mavenBom "org.wildfly.swarm:bom-all:$version"
    }
}

dependencies {
    compile "org.wildfly.swarm:jaxrs"
}

测试主

  package test;

import test.resources.TestResource;
import org.jboss.shrinkwrap.api.ShrinkWrap;
import org.wildfly.swarm.Swarm;
import org.wildfly.swarm.jaxrs.JAXRSArchive;

public class Main {

  public static void main(String... args) throws Exception {

    Swarm swarm = new Swarm();
    JAXRSArchive deployment = ShrinkWrap.create(JAXRSArchive.class);
    deployment.addClass(TestResource.class);
    deployment.addAllDependencies();
    swarm.start();
    swarm.deploy(deployment);
  }
}

我在启动jar时收到此错误:

Wildfly Swarm的gradle插件存在很多问题，例如

https://issues.jboss.org/browse/SWARM-542和

https://issues.jboss.org/browse/SWARM-826

this comment并没有使我确信它们很快就会被修复。

为此，目前我的方法只是假设可靠地使用Gradle构建Swarm应用程序的唯一方法是开始使用Maven构建空心的Swarm uberjar，然后使用Gradle或(我已经完成)，在Docker中。

您会错过自动分数检测(无论如何对于我来说似乎都不起作用)，但另一方面，如果您没有为每个构建都构建整个uberjar，您会获得更快的构建时间。当然，由于Maven显然是Red Hat的一等公民，因此您将自己与不受供应商支持的构建工具脱钩。

有关空心uberjars的更多信息:

https://wildfly-swarm.gitbooks.io/wildfly-swarm-users-guide/content/getting-started/tooling/maven-plugin.html

要使用uberjar部署应用程序，您只需将WAR添加到命令行即可:

java -jar my-hollow-swarm.jar my-application.war

顺便说一句，您还可以传递配置和其他详细信息:

java -jar my-hollow-swarm.jar my-application.war -c /etc/config.xml
java -jar my-hollow-swarm.jar my-application.war --help
