Question

maven是否有任何部署工件的顺序？从我看到我可以说它上传所有工件，最后它更新maven-medata.xml文件

http://localhost:8000/mavenrepository/test1/com/mypackage/mavenproject1/1.0-SNAPSHOT/maven-metadata.xml http://localhost:8000/mavenrepository/test1/com/mypackage/mavenproject1/maven-metadata.xml

现在可以保证maven在上传其他工件后总是最后上传这2个文件吗？

Maven始终以相同的顺序部署工件文件。它通常看起来像这样：

[INFO] --- maven-deploy-plugin:2.7:deploy (default-deploy) @ hello-world ---

正如您所看到的，它首先要做的是尝试在工件级别解析maven-metadata.xml文件，以便弄清楚，如果此工件具有其他版本以及是否生成全新的{{ 1}}文件，或使用它正在部署的新版本更新现有文件（如果有的话）。 maven-metadata.xml文件始终在部署的最后生成或更新。

可以找到maven-metadata.xml个文件的三个级别：

工件级别：此级别为maven-metadata.xml / groupId级别（例如，如果您的artifactId为groupId而您的org.foo.examples为{{1} }}，路径为artifactId）。这用于管理基本版本或发行版本。
版本级别：位于hello-world / org/foo/examples/hello-world/maven-metadata.xml / groupId级别（例如，如果您的artifactId为version且您的{{1} } {是groupId，版本为org.foo.examples，路径为artifactId）。这用于管理带时间戳的快照。
插件组级别：这是插件的hello-world级别，用于管理同一插件组下的不同插件。

在所有上传工件之后，maven是否会部署maven-metadata.xml文件
