使用Karaf特性构建repo-maven-plugin和CXF依赖导致无限循环

Question

我使用的是org.apache.karaf.tooling/features-maven-plugin的2.3.12版本。

当cxf-core和CXF-Commands之间添加循环依赖项时，CXF3.2.x版本似乎已经开始出现这种情况。

它会输出数百个这些，然后抛出堆栈溢出异常：

[INFO] Adding contents for feature: cxf-core/3.2.14
[INFO] Adding contents for feature: cxf-commands/3.2.14
[INFO] Adding contents for feature: cxf-core/3.2.14
[INFO] Adding contents for feature: cxf-commands/3.2.14

下面是我的pom的pom插件部分：

                <groupId>org.apache.karaf.tooling</groupId>
                <artifactId>features-maven-plugin</artifactId>
                    <version>2.4.4</version>
                    <extensions>true</extensions>
                    <dependencies>
                        <dependency>
                            <groupId>org.apache.maven.wagon</groupId>
                            <artifactId>wagon-http-lightweight</artifactId>
                            <version>3.4.1</version>
                        </dependency>
                    </dependencies>
                <executions>
                    <execution>
                        <id>add-features-to-repo</id>
                        <phase>generate-resources</phase>
                        <goals>
                            <goal>add-features-to-repo</goal>
                        </goals>
                        <configuration>
                            <features>
                                <feature>cxf-core/3.2.14</feature>
                            </features>
                        </configuration>
                    </execution>
                </executions>
            </plugin>

这里是cxf特性的冒犯点--注意，“CXF-Core”对“CXF-Commands”特性有条件依赖，而“CXF-Commands”特性对“CXF-Core”有硬依赖。这在我看来是错误的，我看不出有任何方法告诉插件不要进入无限循环。

好吧，事实证明，features-maven-plugin已经被取代了。这个插件起作用了！

                <groupId>org.apache.karaf.tooling</groupId>
                <artifactId>karaf-maven-plugin</artifactId>

只需将目标更改为：features-add-to-repository，并确保设置了。这是正常的一个：

<repository>target/features-repo</repository>

并且，它识别并支持条件功能！
