如果我查看我的 maven 存储库，所有文件都已上传，如日志中所示（它表示已上传文件），但最后构建状态因空指针异常而失败。即使启用调试模式，我也不知道。 请帮忙。
【问题讨论】：
-
奇怪的是
org.apache.maven.plugin.deploy.DeployMojo的第178 行只包含{并且它的cooee 中没有任何内容可能是NPE。 -
您使用哪个版本的 Maven？您使用哪个 JDK 版本？为什么您使用基于
scp的存储库而不是http 之类的？为什么不使用最新版本的 maven-deploy-plugin（当前为 3.0.0）..？除了使用最新版本的 wagon 之外，您是否正确配置为使用 wagon-provider in your pom as extensions？顺便说一句：请显示您的 pom.xml 文件 -
@Steve C，很抱歉没有找到你。
-
@khmarbaise 我正在使用 maven 3.1.1，java 1.8 maven-deploy-plugin 正在使用很长时间。奇怪的是这个构建之前没有抛出错误，但最近开始抛出。
-
当我在 jenkins 上构建我的 maven 工作时，我正面临着确切的问题。你能解决这个问题吗？
