Question

我正在尝试使用ShrinkWrap Dependency Resolver将库添加到我的ShrinkWrap Archive中，以将其部署到服务器进行Arquillian测试。

我正在使用以下pom.xml：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

我的测试看起来像这样：

import java.io.File;

import org.jboss.arquillian.container.test.api.Deployment;
import org.jboss.arquillian.junit.Arquillian;
import org.jboss.shrinkwrap.api.ShrinkWrap;
import org.jboss.shrinkwrap.api.asset.EmptyAsset;
import org.jboss.shrinkwrap.api.spec.WebArchive;
import org.jboss.shrinkwrap.resolver.api.maven.Maven;
import org.jboss.shrinkwrap.resolver.api.maven.MavenResolverSystem;
import org.junit.Test;
import org.junit.runner.RunWith;

import com.itextpdf.text.Document;

@RunWith(Arquillian.class)
public class ResolverTest
{

    @Deployment
    public static WebArchive createDeployment()
    {
        WebArchive jar = ShrinkWrap.create(WebArchive.class)
                .addAsWebInfResource(EmptyAsset.INSTANCE, "beans.xml");

        File[] f = null;

        try
        {
            f = Maven.resolver().resolve("com.itextpdf:itextpdf:5.4.4").withTransitivity().as(File.class);
            jar.addAsLibraries(f);
        }
        catch (Exception e)
        {
            System.out.println(e.getMessage());
            System.exit(1);
        }

        return jar;
    }

    @Test
    public void shouldCreateDocument()
    {
        Document d = new Document();
        d.addAuthor("Marc");
    }
}

如果我不解决itextpdf的依赖性，它会给我发现NoDefClass错误，到目前为止还可以。因此，它希望从pom的依赖项中添加库。从pom中获取它非常重要，因为测试在不同的机器上运行。

使用ShrinkWrap Resolver 2.0.0时出现的错误如下：

java.lang.ClassCastException: Cannot cast org.apache.maven.repository.internal.DefaultVersionResolver to org.sonatype.aether.impl.VersionResolver
    at java.lang.Class.cast(Class.java:3094)
[...]
java.lang.IllegalArgumentException: version resolver has not been specified
    at org.sonatype.aether.impl.internal.DefaultRepositorySystem.setVersionResolver(DefaultRepositorySystem.java:164)
[...]

当我捕捉到所有异常时，还会抛出以下内容：

RuntimeException: Could not create object from user view

我能找到它的来源： https://github.com/shrinkwrap/resolver/blob/master/api/src/main/java/org/jboss/shrinkwrap/resolver/api/ResolverSystemFactory.java

到目前为止，我不知道为什么会收到此错误，因为Google发现的所有消息都告诉我，系统正在运行。任何想法？

看起来这个问题是因为WildFly POM指定了maven-aether-provider的更新版本。在3.1.0（来自WildFly），它依赖org.eclipse.aether:aether-[api|impl|spi]，其中3.0.5（来自Shrinkwrap Resolvers）使用org.sonatype.aether:aether-[api|impl|spi]。如果查看已解析的依赖项，则会在类路径中同时包含ClassCastException。添加以下依赖项应该可以解决此问题：

 <dependency>
   <groupId>org.apache.maven</groupId>
   <artifactId>maven-aether-provider</artifactId>
   <version>3.0.5</version>
   <scope>test</scope>
 </dependency>

使用Arquillian Shrinkwrap Resolver Maven从pom.xml读取依赖项
