我正在尝试使用pax-exam-container-karaf来测试OSGi包。在运行测试时，测试＆＃34;挂起＆＃34;几分钟然后＆＃34;死了＆＃34;除以下例外：

我将Pax-Exam配置为（使用debug == false）：
@Configuration
public Option[] config() throws Exception {
final boolean debug = ConfigurationHelper.getBoolean(
"org.hibernate.testing.osgi.paxExam.debug",
Environment.getProperties(),
DEBUG
);
return options(
when( debug ).useOptions( debugConfiguration( "5005", true ) ),
karafDistributionConfiguration()
.frameworkUrl(
maven()
.groupId( "org.apache.karaf" )
.artifactId( "apache-karaf" )
.type( "tar.gz" )
.versionAsInProject()
)
.unpackDirectory( new File( "target/exam" ) )
.useDeployFolder( false ),
configureConsole()
.ignoreLocalConsole()
.ignoreRemoteShell(),
when( debug ).useOptions( keepRuntimeFolder() ),
logLevel( LogLevelOption.LogLevel.INFO ),
// avoiding additional boot features; specifically "enterprise"
editConfigurationFilePut(
"etc/org.apache.karaf.features.cfg",
"featuresBoot",
"standard"
),
features( hibernateKarafFeatureFile(), "hibernate-native", "hibernate-jpa" )
);
}
我玩过上述配置的各种表现形式，但无法正常工作。
输出显示许多解决工件的问题，例如：
Caused by: shaded.org.eclipse.aether.transfer.ArtifactNotFoundException: Could not find artifact org.ops4j.pax.exam:pax-exam-features:xml:4.5.0
（不是我明确命名的^^），并且：
Caused by: shaded.org.eclipse.aether.transfer.ArtifactNotFoundException: Could not find artifact com.h2database:h2:jar:1.3.170
和
Caused by: shaded.org.eclipse.aether.transfer.ArtifactNotFoundException: Could not find artifact log4j:log4j:jar:1.2.17
等
更重要的是......我从未将这些内容解析为本地Maven缓存。 Karaf（由Pax Exam发起）是否远程找不到这些maven依赖项？我不能说wrt org.ops4j.pax.exam：pax-exam-features：xml：4.5.0，但是log4j和h2 jars以Maven Central中的名字存在。
任何想法我可能缺少什么？
