java - Quartz Scheduler 和对 Karaf 的使用依赖性不启动 OSGi 包

Question

我正在尝试在 Apache Karaf 上使用 Quartz Scheduler:

我在 Apache Karaf Github page 上使用了调度程序示例.

在我的 IDE 上，我执行了一个示例，它工作正常，但我无法在 Karaf 下安装和启动包。

这是包的 POM 导入和导出:

    <Bundle-SymbolicName>${project.artifactId}</Bundle-SymbolicName>
    <Bundle-Version>${project.version}</Bundle-Version>
    <Export-Package>
         com.schedule*;version=${project.version}
    </Export-Package>                        
    <Import-Package>
         !com.mchange.*,
         !oracle.*,
         !org.quartz.management,
         !weblogic.*,
         !javax.transaction,
         *
    </Import-Package>
    <Private-Package>
         org.apache.karaf.scheduler.core,
         org.apache.karaf.scheduler.command.*,
         org.quartz,
         org.quartz.core.*,
         org.quartz.listeners.*,
         org.quartz.impl.*,
         org.quartz.spi.*,
         org.quartz.simpl.*,
         org.quartz.utils.*,
     </Private-Package>

问题是 Karaf 导入包和排除项。这是 Karaf 日志:

感谢您的帮助，包装 Quartz jar 可以帮助解决此问题并将依赖项用作 jar。这就是为什么我们需要这些依赖项:

   <dependency>
        <groupId>org.apache.servicemix.bundles</groupId>
        <artifactId>org.apache.servicemix.bundles.quartz</artifactId>
        <version>2.2.3_1</version>
    </dependency>

    <dependency>
        <groupId>org.quartz-scheduler</groupId>
        <artifactId>quartz</artifactId>
        <version>2.2.3</version>
    </dependency>

    <dependency>
        <groupId>c3p0</groupId>
        <artifactId>c3p0</artifactId>
        <version>0.9.5.2</version>
    </dependency>

要在 Karaf 中安装它，我们可以使用这些带有 wrap 前缀的命令:

 bundle:install wrap:mvn:c3p0/c3p0/0.9.1.2
 bundle:install mvn:org.quartz-scheduler/quartz/2.2.2
 bundle:install wrap:mvn:org.quartz-scheduler/quartz-jobs/2.2.2
