【问题描述】：

我们遇到了阻碍我们的问题。我们在 Apache karaf 3.0.3、cellar 3.0.3 中的项目运行良好。现在我们升级到 Apache karaf 4.2.0 和 Apache cellar 4.1.0。我看到了这个错误

[activator-1-thread-2] 错误 org.apache.karaf.features.internal.service.BootFeaturesInstaller - 安装引导功能时出错 org.osgi.service.resolver.ResolutionException：无法解析根：缺少需求 [root] osgi.identity； osgi.identity=OUR_FEATURE; 类型=karaf.feature；版本="[18.12.4,18.12.4]"; filter:="(&(osgi.identity=OUR_FEATURE)(type=karaf.feature)(version>=18.12.4)(version[引起：无法解析 com.hazelcast/3.8.1：缺少要求 [com.hazelcast/3.8.1] osgi.wiring.package； filter:="(osgi.wiring.package=sun.misc)"]]]]]*

正如我们所见，错误来自 com.hazelcast，版本 3.8.1

确实，过去我们使用 karaf cellar 和 karaf 3.0.3，他们使用 com.hazelcast/hazelcast/version 3.4。 2 (https://mvnrepository.com/artifact/com.hazelcast/hazelcast/3.4.2)

现在有了 karaf 4.2.0 和 cellar 4.1.0，他们使用 com.hazelcast/hazelcast-all/3.8.1 https://mvnrepository.com/artifact/com.hazelcast/hazelcast-all/3.8.1 而这个版本导致了这个错误

这是我们的 features.xml 文件的内容

<repository>mvn:org.apache.karaf.cellar/apache-karaf-cellar/4.1.0/xml/features</repository>
<feature name="OUR_FEATURE" version="18.12.4" description="Our description">

    <feature version="${project.version}">other_features</feature>

安装后我们尝试在目标目录中搜索（mvn clean install）并在目标文件夹中找到这些功能

在我们的 src/main/distribution/etc/config.properties 中，我们已经有以下配置： org.osgi.framework.system.packages.extra=sun.misc

org.osgi.framework.bootdelegation=org.apache.karaf.jaas.boot,org.apache.karaf.jaas.boot.principal,org.apache.karaf.management.boot,sun.,com .sun.,javax.transaction,javax.transaction.,javax.xml.crypto,javax.xml.crypto.

在我们的 src/main/distribution/etc/custom.properties 中，我们有以下配置：

karaf.systemBundlesStartLevel=50 org.osgi.framework.system.packages.extra = org.apache.karaf.branding

请帮助我们解决这个问题。

非常感谢

【解决方案1】：

当包加载类但没有为它们定义 Import-Package 语句时使用引导委托。

在您的情况下，hazelcast 有一个 Import-Package 声明。因此，要完成这项工作，您必须从系统捆绑包中导出包。

为此，请编辑config.properties 并将sun.misc 添加到org.osgi.framework.system.packages.extra。

非常感谢您的回答。如您所见，我已经写过：“在我们的 src/main/distribution/etc/config.properties 中，我们已经有以下配置：org.osgi.framework.system.packages.extra=sun.misc” 但它不起作用.所以我尝试使用引导委托，它也不起作用
从系统包中导出是唯一可行的方法。也许配置中有一个小错误，它没有被处理。我刚刚启动了一个普通的 karaf 4.2.0 并安装了事务功能和 hazelcast 包。它开箱即用。 sun.misc 包已经导出。
感谢您的回答。你把你的config.properties放在哪里？我的目录布局类似于 my-deployement/pom.xml my-deployement/src/main/distribution/binaries/setenv my-deployement/src/main/distribution/etc my-deployement/src/main/distribution/filtered-resources这是 my-deployement/src/main/distribution/etc 文件夹中的文件列表： - config.properties、custom.properties、keys.properties、org.apache.cxf.osgi.cfg、org.apache.karaf.management .cfg、org.apache.karaf.shell.cfg、org.ops4j.pax.url.mvn.cfg、org.ops4j.pax.web.cfg、system.properties、user.properties
这里是 my-deployement/src/main/distribution/etc 文件夹中的文件列表： - config.properties,custom.properties,keys.properties,org.apache.cxf.osgi.cfg , org.apache.karaf.management.cfg, org.apache.karaf.shell.cfg, org.ops4j.pax.url.mvn.cfg, org.ops4j.pax.web.cfg, system.properties, user.properties
这里是 my-deployement/src/main/distribution/filtered-resources 中的文件列表：org.apache.karaf.cellar.groups.cfg, org.apache.karaf.cellar.node .cfg、org.apache.karaf.features.cfg、org.ops4j.pax.logging.cfg

这是我的 config.properties 的提取
