将 <dependency> 添加到我的 Atlassian 插件的 pom.xml 会导致 Spring BundleException 违反约束答案

【问题标题】：Adding a <dependency> to my Atlassian plugin's pom.xml causes a Spring BundleException with a Constraint violation将 <dependency> 添加到我的 Atlassian 插件的 pom.xml 会导致 Spring BundleException 违反约束
【发布时间】：2014-10-28 21:15:00
【问题描述】：

我正在为 Atlassian Confluence 编写一个插件。我已经让它在开发环境中工作了很长一段时间。但是，当我将插件打包并将其部署到测试系统中时，插件无法启用。我在堆栈跟踪中看到以下原因/错误消息（完整包含在此问题的末尾）。为了便于阅读，我已对其进行了格式化：

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)
        ]

我无法理解这试图告诉我什么。 Confluence OSGi 容器调试信息为所提到的包指明以下内容：

0 - 系统包

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该消息或如何解决问题。

新信息：

该插件适用于 Confluence 5.5.4，但适用于 5.6.4。
我创建了一个新的空生成插件 (atlas-create-confluence-plugin) 并小心地将我的每个依赖项添加到 pom.xml 中，直到我能够产生失败。当我添加此依赖项时，显然会导致失败：

com.foo JMS工具 1.0-快照 org.slf4j slf4j-api javax.mail 邮件日志4j 日志4j

这是我写的一个库。虽然它本身不使用 Spring 进行配置，但某些对象实现了 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。

我刚刚尝试将 JMSTools 使用的版本更改为 2.5.6.SEC03，但仍然没有解决问题。即使确实如此，我也会担心未来的更新 Confluence 可能会更新 Spring 并再次破坏。我的库不依赖于特定版本的 Spring，它只需要实现/使用我之前提到的类和接口。

我目前的怀疑是 org.apache.activemq:activemq-all（JMSTools 的依赖项）可能由于某种原因引用了 org.springframework.jms.connection，从而导致了冲突。但是....我只是不知道（还）。

对 Scott Dudley 问题的回答：

(a) Confluence 版本：

5.6.4

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 中有组件导入以在 atlassian-plugin-context.xml 中引用它们。如果没有，我可以稍微清理一下这些列表。

(d) public=true 的组件：

<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。我唯一暴露的是：

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

【问题讨论】：

您的 pom.xml 或 atlassian-plugins.xml 中是否有任何明确的 OSGi 导入说明？如果是这样，你能把它们贴出来吗？（另外，您似乎在帖子末尾省略了堆栈跟踪。）我读到的错误是提供了 Spring 事务包的 v4，但也许您提供了“[0.0.0,0.0 .0]" 明确排除它。
噢，我确实忘记了堆栈跟踪。对于那个很抱歉。（一旦我的应用程序恢复到再次出现此特定错误的位置，我将更新问题。）我的 pom.xml 或 atlassian-plugins.xml 中没有任何 OSGi 导入说明。据我所知，Confluence 本身在系统包和 spring 框架包中加载（提供？我不确定这里的术语）org.springframework.transaction。他们确实有不同的版本。请注意，我认为 4.0.org.springframework.transaction 指的是捆绑包 4，而不是版本 4。
哦——我认为你对“4”的看法是正确的。如果您不提供特定的 OSGi 捆绑指令，那么 Confluence 会在插件安装时通过扫描您的 JAR 自动构建它们。在堆栈跟踪的顶部，您能否还发布：（a）您的 Confluence 版本，（b）您的 pom.xml 中的 <dependency> 列表，（c）atlassian-plugin.xml 中的 <component-import>s，以及(d) atlassian-plugin.xml 中的任何<component> public=true?
我还注意到错误中提到的“使用约束”。这对我来说也是新的 OSGi 领域，但这看起来很相关：njbartlett.name/2011/09/02/uses-constraints.html
Scott，我已编辑问题以添加新信息并回答您的问题。我也会阅读该链接。感谢您的帮助！

【解决方案1】：

仅仅将<dependency> 条目添加到否则为空的插件中的pom.xml 通常不会导致插件加载时出现 OSGi 错误，因为 Confluence 不应该仅仅基于依赖项的存在来尝试导入外部包。

我的怀疑（在聊天线程中得到确认）是您的依赖项之一包含某种 Spring 指令，这会混淆 Confluence 在插件加载方面的问题。当使用默认值构建插件时，插件 SDK 将自动取消 JAR 所有依赖项并将生成的文件集包含在主插件 JAR 中。

如果您的某个库依赖项无意中在 META-INF/spring 或其他地方包含 Spring 相关数据，这将与您自己的插件的 Spring 配置混合在一起，这可能会造成严重破坏。

解决此问题的最佳方法是禁用依赖项提取。这意味着，不是取消所有依赖项的 JAR 并将它们转储到与插件相同的 JAR 中，而是将依赖项留在它们的源 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，它们也会保留在自己的 JAR 中，并且在加载插件时不会被 Confluence 处理。

要禁用提取依赖项，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-conflue‌‌nce-plugin</artifactId>
    <version>x.y.z</version>
    [...]
    <configuration>
        [...]
        <extractDependencies>false</extractDependencies>
    </configuration>
</plugin>

【讨论】：

这就像一个魅力！非常感谢您的所有帮助。
Scott 对这里发生的事情进行了很好的描述。我还建议将 extractDependencies 切换为 false，这样您的 jar 中就不会出现太多混乱。显然，提取依赖项加快了插件的启动时间，但该死的，它使事情变得不整洁，而且有时会弄乱 Spring 配置。
