java - 预装 pax-jdbc-oracle 的自定义 Apache Karaf 4.0.4 发行版

Question

我正在尝试构建一个带有一些预装功能的自定义 karaf 发行版，因为我们没有互联网来部署它。

这是我们的 pom:

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

<artifactId>karaf</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>karaf-assembly</packaging>

<properties>
    <karaf.version>4.0.4</karaf.version>
    <!-- Karaf Maven Plugin does not have to be same as Karaf Server version
         For example, Karaf Maven Plugin 3.0.2 has bug uploading to password protected Nexus Repo
         So I used Karaf Maven Plugin 3.0.3 to build a Karaf 3.0.2 Server -->
    <karaf.plugin.version>${karaf.version}</karaf.plugin.version>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.build.reportEncoding>UTF-8</project.build.reportEncoding>
</properties>

                <!-- installedFeatures only installs the libraries in the ${KARAF_HOME}/system directory
                     but the user will have to start it up manually via Karaf command line feature:install
                -->
                <installedFeatures>
                    <feature>pax-jdbc</feature>

            </configuration>
        </plugin>
    </plugins>
</build>

我们总是收到以下错误:

我们希望预安装此功能，但不知何故，将其放在 bootFeatures 或InstalledFeatures 下并不重要。

提供的范围/运行时也并不重要。

由于许可原因，pax-jdbc-oracle 功能无法打包 oracle jdbc 驱动程序。您必须提供自己的副本，并将其包含在您的发行版中。该驱动程序无法在 Maven Central 中访问，并且没有许可证就无法下载。
