我在哪里为Bitbucket上托管的Maven项目上的Azure DevOps管道设置Nexus凭据？

Question

我正在尝试为使用Maven的Java项目创建简单的管道。我项目的.jar依赖项全部托管在受密码保护的在线Nexus上。我正在构建的源托管在Bitbucket上。

我似乎找不到如何告诉管道要用于Nexus的凭据的凭据。

这是我的Maven任务结果：

它说验证失败并且未经授权。当我从自己的本地计算机上运行生成时，它确实可以工作，因为我的.m2文件夹中有一个带有凭据的settings.xml文件，但如何使它在Azure DevOps中运行？

您可以尝试使用Maven Authenticate任务添加一个Maven service connection以连接到您的外部Maven存储库。以下步骤仅供参考。

转到项目设置-> 管道->单击服务连接->单击新服务连接->选择Maven- >输入您的Nexus存储库所需的信息。

然后在管道中，在Maven任务之前添加Maven Authenticate任务，以提供将在以下Maven任务中使用的外部Maven存储库的凭据。

由于只需要对外部nexus maven存储库进行身份验证，因此可以将Feeds字段保留为空白。然后单击下面突出显示的下拉列表，以选择您在上述步骤中创建的nexus的Maven服务连接。

完成上述步骤后，您的maven任务应该能够从nexus下载jar依赖项。
