Sucesive builds triggered by this plugin are causing the previous one not to be seen in the UI at byuild history (see attached file).
The builds are in the filesystem tough. Just not seen.. only the last one. And if I reload jenkins form disk conf, even the last one dissapears in the UI.

In the attached file, jobs 77 to 79 were previous runs from the plugin. Only the last one is sen (80). After a reload from disk, even this one is gone.

They all are visible in filesystem as builds folders, and they all contain build.xml and all looks normal:
```sh
ls -1
72
73
74
75
76
77
78
79
80
```
Thanks for checking this, the plugin is really useful and I want to use it, but this bug is preventing me to use it..
