添加一个 我的Atlassian插件的pom.xml导致Spring BundleException出现Constraint违规

Question

我正在为Atlassian Confluence编写一个插件。我已经在开发环境中工作了很长一段时间。但是，当我打包插件并将其部署到测试系统时，插件无法启用。我在堆栈跟踪中看到以下原因/错误消息（在本问题的最后部分包含在内）。我把它格式化为稍微容易阅读：

Caused by: org.osgi.framework.BundleException: 
    Constraint violation for package 'org.springframework.transaction' when resolving module 200.0 between existing import 0.org.springframework.transaction 
    BLAMED ON 
        [
            [200.0] package; 
            (&(package=org.springframework.transaction)(version>=0.0.0)(version<=0.0.0))
        ] 
        and uses constraint 4.0.org.springframework.transaction
    BLAMED ON 
        [
            [200.0] package;
            (package=org.springframework.jms.connection)
        ]

我无法理解这是想告诉我的。 Confluence OSGi容器调试信息指出所提到的包的以下内容：

0 - 系统捆绑

4 - Spring框架

200 - com.foo.ConflunceJMSIntegration（我的插件）

我怀疑这与各种模块使用的类加载器有关，但我只是不知道如何解释消息或如何解决问题。

新的消息：

• 该插件适用于Confluence 5.5.4，但在5.6.4时失败。
• 我创建了一个新的空生成插件（atlas-create-confluence-plugin）并小心地将每个依赖项添加到pom.xml中，直到我能够生成失败。添加此依赖项时，显然会导致失败： com.foo JMSTools 1.0-SNAPSHOT org.slf4j slf4j-api javax.mail mail log4j log4j

这是我写的图书馆。虽然它不使用Spring进行配置本身，但是一些对象实现org.springframework.beans.factory.DisposableBean并使用org.springframework.util.StringUtils，因此Spring是合法的要求。

这是JMSTools中的依赖：

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-beans</artifactId>
    <version>2.5.6.SEC02</version>
    <scope>provided</scope>
</dependency>

而且......现在我输入了这个，我看到Confluence 5.6.4使用org.springframework：spring-core：jar：2.5.6.SEC03-atlassian-6：compile。

我只是尝试将JMSTools正在使用的版本更改为2.5.6.SEC03，但它仍然无法解决问题。即使它确实如此，我也会担心未来的更新Confluence可能会更新Spring并再次破坏它。我的库不依赖于Spring的特定版本，它只需要实现/使用我之前提到的类和接口。

我当前的怀疑是org.apache.activemq：activemq-all（JMSTools的依赖项）可能由于某种原因引用org.springframework.jms.connection，不知何故导致冲突。但是......我只是不知道（还）。

注意：我需要检查以确保我仍然需要所有这些导入/引用。我也不确定是否需要在atlassian-plugin.xml中使用component-import来在atlassian-plugin-context.xml中引用它们。如果没有，我可能会稍微清理这些列表。

(d) components where public=true:

<component key="confluence-event-listener" class="com.foo.confluence.ConfluenceJMSAnnouncerImpl"
           name="Confluence Event Listener" i18n-name-key="confluence-event-listener.name" public="true">
    <description key="confluence-event-listener.description">The confluence event listener Impl Plugin</description>
    <interface>com.foo.confluence.ConfluenceJMSAnnouncer</interface>
</component>

注意：我怀疑这不需要公开。

第二点：我在atlassian-plugin-context.xml中配置了30个bean。我揭露的唯一一个是：

<osgi:service interface="com.foo.confluence.ConfluenceService" ref="confluenceService"/>

仅仅在一个空的插件中将<dependency>条目添加到pom.xml通常不会导致插件加载时出现OSGi错误，因为Confluence不应该仅仅根据依赖项的存在来尝试导入外部包。

我的怀疑（在聊天线程中得到证实）是你的一个依赖项包含某些类型的Spring指令，这些指令会让Confluence对插件加载感到困惑。当使用默认值构建插件时，插件SDK将自动解除对所有依赖项的JAR，并在主插件JAR中包含生成的文件集。

如果你的某个库依赖项无意中包含了META-INF/spring或其他地方的Spring相关数据，那么这将与你自己的插件的Spring配置混合在一起，这会造成严重破坏。

解决此问题的最佳方法是禁用依赖项提取。这意味着，不是将所有依赖项取消JARring并将它们转储到与插件相同的JAR中，而是依赖项保留在它们的源JAR中，并且这些JAR直接包含在META-INF/lib中。即使依赖项确实声明了一些流氓Spring指令，它们仍会保留在自己的JAR中，并且在加载插件时Confluence不会处理它们。

要禁用依赖项的提取，您需要在pom.xml的confluence-maven-plugin部分中将extractDependencies设置为false，如下所示：

<plugin>
    <groupId>com.atlassian.maven.plugins</groupId>
    <artifactId>maven-conflue‌​‌​nce-plugin</artifactId>
    <version>x.y.z</version>
    [...]
    <configuration>
        [...]
        <extractDependencies>false</extractDependencies>
    </configuration>
</plugin>
