Jenkins API 抛出 IOException : Failed to persist config. xml

Question

我正在尝试在 Ubuntu 17.10 上使用 Jenkins API 和curl 创建一个新作业。我正在按照 this thread 上的示例进行操作。创建面包屑效果很好。但是，创建作业的调用失败，并出现堆栈跟踪，其根本原因是:

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]

还尝试了这种变体，尝试传递基本的 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

只是发布一个答案，其中包含我作为评论指出的内容。看起来整个堆栈跟踪丢失了，第一行读取 caused...这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 line 292 ，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 <jenkins instance root>/api/ 获取。 :

To create a new job, post config.xml to this URL with query parameter name=JOBNAME. You need to send a Content-Type: application/xml header. You will get a 200 status code if the creation is successful, or 4xx/5xx code if it fails. config.xml is the format Jenkins uses to store the project in the file system, so you can see examples of them in the Jenkins home directory, or by retrieving the XML configuration of existing jobs from /job/JOBNAME/config.xml.
