问题描述
我们的构建包括两个项目，一个库项目和一个依赖于库项目的Web前端项目.
Our build consists of two projects, a library project and a web front end project that depends on the library project.
Hudson作业是从maven pom.xml文件配置的，并且依赖项在Hudson上显示为下游/上游项目.这两个作业都使用"poll SCM"构建触发器，并且只有一个项目发生更改时，一切都会按预期进行.
The Hudson jobs are configured from the maven pom.xml files and the dependency appears on Hudson as downstream/upstream project. Both jobs use the "poll SCM" build trigger and everything works as intended when only one the projects changes.
当提交包含两个项目中的更改时，就会出现问题，因此Hudson同时启动两个项目的构建，并且通常Web项目构建失败，因为它使用的是库项目的旧版本.
The problem arises when a commit contains changes in both projects, so Hudson starts a build of both projects at the same time and usually the web project build fails because it is using an older version of the library project.
如果存在运行库项目的构建，我可以配置Hudson来延迟Web项目构建的执行吗?
Can I configure Hudson to delay the execution of the web project build if there is a build running the library project?
推荐答案
Web项目和其他项目不是位于版本控制的不同区域吗?另一方面，您可以定义上游或下游依赖关系，并且仅在构建顺利的情况下才说开始.
Isn't the web project and the other project located in a different area of the version control? ON the other hand you can define upstream or downstream dependencies and say only start if the build went well.
