Blueprint-使用Pax Exam进行单元测试-无法解决依赖关系

Question

我们正在将基于spring的camel应用程序迁移到基于蓝图的camel应用程序。我们还将迁移到fuse 6.1版本。我正在使用带有Junit runner的Pax考试和apache felix容器来执行我的单元测试。我面临与ehcache manager相关的未解决捆绑包问题。我曾尝试将pax配置作为mavenBundle提供所需的依赖性，但没有任何运气。异常并没有给出缺少依赖项的细节，而是只给出了包的一般错误，即“osgi.willing.package=net.sf.ehcache”<我在pom中给出了必要的依赖性。xnl和eclipse没有显示任何错误。下面是Junit中使用的配置。

“@Configuration public Option[]config（）{

    return options(systemProperty("org.ops4j.pax.logging.DefaultServiceLog.level").value("DEBUG"),
            systemProperty("Test.Property").value("system"),
            systemProperty("pax.exam.logging").value("none"),
            systemTimeout(600000),

            mavenBundle("commons-lang", "commons-lang", "2.5"),
            mavenBundle("commons-collections", "commons-collections", "3.2.1"),
            mavenBundle("commons-beanutils", "commons-beanutils", "1.8.3"),
            mavenBundle("commons-io", "commons-io", "2.0"),
            mavenBundle("ch.qos.logback", "logback-core", "1.0.9"),
            mavenBundle("ch.qos.logback", "logback-classic", "1.0.9"),
            mavenBundle("org.slf4j", "slf4j-api", "1.7.5"),
            mavenBundle("org.slf4j", "jcl-over-slf4j", "1.7.5"),
            mavenBundle("net.sf.ehcache", "ehcache-core", "2.6.9"),
            mavenBundle("net.sf.ehcache", "ehcache", "1.5.0"),
            mavenBundle("org.apache.aries.blueprint", "org.apache.aries.blueprint", "1.1.0"),
            mavenBundle("org.apache.aries.proxy", "org.apache.aries.proxy", "1.0.0"),
            mavenBundle("org.apache.aries", "org.apache.aries.util", "1.1.0"),
            mavenBundle("channelservicelayer", "base", "1.0.0"),
            mavenBundle("asm", "asm-all", "3.1"),
            junitBundles()
            );
}'

我附上日志如下

Answer 1

我通过将ehcache版本升级到2.8.5的最新版本，成功地解决了这个问题。ehcache core期望的版本比我使用的1.5.2版本的ehcache要高
对于像我这样的osgi初学者来说，更大的问题是没有得到正确的错误消息，这让我不得不花很多时间进行调查。
