Maven 安装失败：安装看不到打包的工件

Question

尽管文件存在（并且是在 package 阶段创建的），但我的 Maven 构建在 install 阶段失败并出现 No such file or directory 错误。

文件系统确认 /home/username/artifactname/sphinxsegmentation/target/artifactname-segmenter-0.0.1-SNAPSHOT-downstream-test-input.zip 存在于文件系统上，并且仅通过 package 阶段执行成功。

除默认的 maven-install-plugin 外，没有插件绑定到安装阶段。 artifactname-segmenter-0.0.1-SNAPSHOT-downstream-test-input.zip 由具有以下 descriptorRefs:

的 maven-assembly-plugin 执行生成

为什么安装时看不到 zip 工件？感谢您的帮助。

Answer 1

问题出在 build-helper-maven-plugin 的父 POM 配置中，出于某种原因，它通过名称 target/${project.name}-${project.version}-downstream-test-input.zip 引用了工件。 <name> 设置为 artifactname-segmenter 而 artifactId 设置为 artifactname-segmentation。

检查您的配置，伙计们。
