java - Maven 处理 Nexus 异常

Question

我有一个项目，其中有多个子项目(模块)。更具体地说，这是一个 Eclipse 项目，具有多种功能。

问题是某个版本的功能可能不需要任何更改。因此，我不会提高版本号，但同一项目中的另一个功能可能会发生变化。由于重新部署相同版本被认为是不好的做法，因此我在 Nexus 中禁用了该选项。

现在，实际问题发生在我部署时。因此，部署任何具有新版本号的东西都可以正常工作，但是当部署旧版本时，我有点期待 Maven 发出警告，警告它已经存在于存储库中，然后跳过它，但事实证明 Nexus 响应:

Return code is: 400, ReasonPhrase:Bad Request.

这会导致 Maven 整个部署过程失败。完整的错误是:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.5:deploy (default-deploy) on project xyz: Failed to deploy artifacts: Could not transfer artifact xyz:target:2.5.8.0 from/to nexus (http://host/nexus/content/repositories/releases): Failed to transfer file: http://host/nexus/content/repositories/releases/x/targets/xyz/2.5.8.0/xyz-2.5.8.0.target. Return code is: 400, ReasonPhrase:Bad Request. -> [Help 1]
build   11-Sep-2015 07:09:57    [ERROR] Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.5:deploy (default-deploy) on project abc: Failed to deploy artifacts: Could not transfer artifact foo:abc:jar:2.5.8.0 from/to nexus (http://host/nexus/content/repositories/releases): Failed to transfer file: http://host/nexus/content/repositories/releases/bar/abc/2.5.8.0/abc.ocl-2.5.8.0.jar. Return code is: 400, ReasonPhrase:Bad Request. -> [Help 1]

问题是，我该如何处理这个失败/异常？我想要的只是如果它已经部署，然后跳过/忽略该 Artifact 的部署。

参见Maven: The Complete Reference, 6.1. Maven Command Line Options, 6.1.8. Dealing with Failure或mvn --help:

-fae,--fail-at-end    Only fail the build afterwards;
                      allow all non-impacted builds to
                      continue
