Maven 捆绑包打包问题，称为 MNG-4338

Question

我在使用 maven-bundle-plugin 时遇到了问题：

我想将我的项目部署为 osgi 包，因此我将打包用作包。 但似乎 pom 不知道将包装作为捆绑包。在这里你可以看到我的pom.xml：

<project ...>...
    <packaging>bundle</packaging>
<version>1.0.0</version>

<name>Simple CXF project using spring configuration</name>

<properties>
    <cxf-version>2.4.2</cxf-version>
</properties>

<build>
    <pluginManagement>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>
                    <source>1.5</source>
                    <target>1.5</target>
                </configuration>
            </plugin>
            <plugin>
                <groupId>org.apache.felix</groupId>
                <artifactId>maven-bundle-plugin</artifactId>
                <extensions>true</extensions>
                <version>2.3.5</version>
                <configuration>
                    <instructions>
                        <Bundle-SymbolicName>${project.groupId}.${project.artifactId}</Bundle-SymbolicName>
                        <Bundle-Name>${project.name}</Bundle-Name>
                        <Bundle-Version>${project.version}</Bundle-Version>
                        <Export-Package>demo.hw.server</Export-Package>
                        <Bundle-Activator>demo.hw.server.Activator</Bundle-Activator>
                        <Require-Bundle>org.apache.cxf.bundle</Require-Bundle>
                    </instructions>
                </configuration>
            </plugin>
        </plugins>
    </pluginManagement>
</build>

<dependencies>
    <dependency>
        <groupId>org.apache.cxf</groupId>
        <artifactId>cxf-rt-frontend-jaxws</artifactId>
        <version>${cxf-version}</version>
    </dependency>
    <dependency>
        <groupId>org.apache.cxf</groupId>
        <artifactId>cxf-rt-transports-http</artifactId>
        <version>${cxf-version}</version>
    </dependency>
    <dependency>
        <groupId>org.apache.felix</groupId>
        <artifactId>org.osgi.core</artifactId>
        <version>1.4.0</version>
    </dependency>
</dependencies>

</project>

他们说，这个错误已经被修复（http://jira.codehaus.org/browse/MNG-4338），但对我来说似乎还没有。以前有人遇到过这个问题并找到解决方案吗？

错误消息是这样的：

[INFO] Scanning for projects...
[ERROR] The build could not read 1 project -> [Help 1]
[ERROR]   
[ERROR]   The project com.talend.liugang.cxf:java_first_jaxws:1.0.0 (C:\Users\Andreas\workspace\java_first_jaxws\pom.xml) has 1 error

最好的问候， 萨恩

Answer 1

鉴于上面的 pom 示例，您应该将 maven-bundle-plugin 移到 节点之外。 通常用于父 pom 中的继承目的。包打包类型由 maven-bundle-plugin 提供（这就是为什么你需要 true），所以这个插件需要在 之外。在这种情况下，pluginManagement>。

<project ...>...
    <packaging>bundle</packaging>
    <version>1.0.0</version>

    <name>Simple CXF project using spring configuration</name>

    <properties>
        <cxf-version>2.4.2</cxf-version>

                    </configuration>
                </plugin>
            </plugins>
        </pluginManagement>

Answer 2

是的，问题是org.apache.felix需要位于之外。

Answer 3

我看到类似的问题。我发现，当组 id 结束（就像工件 id 开始一样）时，就会发生这种情况。我尝试捆绑类似的东西：

<groupId>org.slf4j</groupId>
<artifactId>slf4j-api.plugin</artifactId>

工件 id 中的 slf4j 被删除，最终结果如下：清单中的 org.slf4j.api.plugin 作为符号名称。
