如何在目标执行期间调试第三方 maven 插件？

Question

我在我的代码中使用了以下插件：

            <plugin>
            <groupId>external.atlassian.jgitflow</groupId>
            <artifactId>jgitflow-maven-plugin</artifactId>
            <version>1.0-m5.1</version>
            <configuration>
                <username>${bbuser}</username>
                <password>${bbpw}</password>
                    <flowInitContext>
                        <masterBranchName>master</masterBranchName>
                        <developBranchName>develop</developBranchName>
                        <featureBranchPrefix>SPRINT-</featureBranchPrefix>
                        <releaseBranchPrefix>release-</releaseBranchPrefix>
                        <hotfixBranchPrefix>hotfix-</hotfixBranchPrefix>
                    </flowInitContext>
            </configuration>
            </plugin>

要执行它，我执行以下操作：

 mvn -e -X -B -Dbbuser=$env.GIT_USERNAME -Dbbpw=$env.GIT_PASSWORD -DnoDeploy=true -DnoReleaseBuild=true -DpushReleases=true jgitflow:release-start

这在本地有效，但在 Jenkins 中我得到以下异常：

    [ERROR] Failed to execute goal external.atlassian.jgitflow:jgitflow-maven-plugin:1.0-m5.1:release-start (default-cli) on project steeringcockpit: Execution default-cli of goal external.atlassian.jgitflow:jgitflow-maven-plugin:1.0-m5.1:release-start failed: String index out of range: -6 -> [Help 1]

我想以某种方式调试插件的执行，使用 mvnDebug 和 Eclipse 调试器在此行设置断点以检查本地发生的情况。问题是我不知道如何将插件的源附加到我的 eclipse 环境中，我什至无法在本地存储库中找到插件源。

如果我可以在 jenkins 中调试它会更加酷。这可能吗？

源代码有： https://bitbucket.org/atlassian/jgit-flow/src/1.0-m5.1/（适用于您的插件版本）

请克隆/下载jgit-flow到本地机器，在你的Eclipse中打开项目作为新项目。现在可以为插件代码设置断点了。

在 Eclipse 中为 8000 端口的 localhost 准备远程调试配置。

在单独的 ide / 控制台中，在您的项目上运行 mvnDebug，当您看到类似以下内容时：

Preparing to execute Maven in debug mode
Listening for transport dt_socket at address: 8000

使用打开的插件代码在 Eclipse 中启动调试会话
