Jenkins API抛出IOException:无法持久化config.xml

Question

我正在尝试使用带有curl的Jenkins API在Ubuntu 17.10上创建一个新工作.我正在关注这个帖子的例子.创造面包屑效果很好.但是,创建作业的调用失败,并带有根本原因的堆栈跟踪:

[编辑添加堆栈跟踪的其余部分]

脚本文件是:

CRUMB=$(curl -s 'http://<redacted>@localhost:8080/crumbIssuer/api/xml?xpath=concat(//crumbRequestField,":",//crumb)')

echo ${CRUMB}

curl -X POST -H "$CRUMB" -H "content-type:application/xml" "http://<redacted>@localhost:8080/createItem?name=NewJob2"

[编辑]

也试过这个变种,试图传递一个基本的config.xml文件:

curl -X POST -H "$CRUMB" -H "content-type:application/xml" --data "@config.xml" "http://helo478:5ccf2750debe105962b1bf3a8483cfd8@localhost:8080/createItem?name=Test" --trace-ascii /dev/stdout

Answer 1

只是用我作为评论指出的内容发布答案。看起来整个堆栈跟踪丢失了，读取的第一行caused...表明异常还有更多内容。

此外，我查看了第一个堆栈跟踪帧的源代码， hudson.model.ItemGroupMixIn.createProjectFromXML第 292 行，从那里很明显，上传的 XML 文件有问题，显然根本没有上传。

来自 Jenkins API 文档，可在以下位置获取<jenkins instance root>/api/：

要创建新作业，请将 config.xml 发布到此 URL，并使用查询参数 name=JOBNAME。您需要发送 Content-Type: application/xml 标头。如果创建成功，您将获得 200 状态代码，如果失败，您将获得 4xx/5xx 代码。config.xml 是 Jenkins 用于在文件系统中存储项目的格式，因此您可以在 Jenkins 主目录中查看它们的示例，或者通过从 /job/JOBNAME/config.xml 检索现有作业的 XML 配置来查看它们的示例。
