java - Jenkins 构建失败，出现 IOException : Failed to parse changelog

Question

如何找到根本原因？下面的堆栈跟踪:

[workspace] $ /usr/atria/bin/cleartool catcs -tag XXXXX
element * CHECKEDOUT
element * .../XXXXsupport_2.2/LATEST
element * /main/LATEST -mkbranch XXXXsupport_2.2
load /vobs/XXXX
java.io.IOException: Failed to parse changelog

Answer 1

有一个固定的JENKINS-33433问题

jobs fail to "parse changelog" for pull requests with "catch-up" merges from destination branch]1

修复应该包含在 2017 年 8 月的 5.2 正式版本或最新 beta 5.1.0.2(发布到 Jenkins 实验更新中心)中
