[aerogear-dev] Random Jenkins failures when building UPS

Hi all, while using the latest version of the UnifiedPush Server (0.11.0), that includes the new frontend-maven-plugin to build the admin-ui module, I was experiencing random failures when building with Jenkins. I have googled for a while, and found that the problem was in the concurrent modification of the bower cache and registry. I tried one solution suggested in (https://github.com/bower/bower/issues/933), so I changed the admin-ui/.bowerrc file and added the following: "storage": { "packages": ".bower-cache", "registry": ".bower-registry" }, "tmp": ".bower-tmp" , so admin-ui/.bowerrc ending with this content: { "directory": "app/bower_components" "storage": { "packages": ".bower-cache", "registry": ".bower-registry" }, "tmp": ".bower-tmp" } This made my Jenkins build stable, and I did not experience random failures anymore (ran 10 subsequent builds without errors, while I could not run 2 successful subsequent builds before). However, digging more into the thread, I found that the problem of the race condition against the bower cache was solved in bower version >= 1.3.2 (https://github.com/bower/bower/pull/1211). Actually in admin-ui/package.json we have "grunt-bower-task": "^0.3.4", that would download a bower version >= 1.2.0 (looking in my Jenkins build, it downloaded bower version 1.2.8), which is not enough for having the problem fixed. So I explicitly forced bower version to be at least 1.3.2, by adding: "bower": "~1.3.2" into admin-ui/package.json. The solution is working for me, and I also removed the additional content inside the file admin-ui/.bowerrc that I added before. I also found another project that solved the problem in this way: https://github.com/opf/openproject/commit/36d2e9079b23955d3a1198ec1a8698c... I have opened a PR for this (https://github.com/aerogear/aerogear-unifiedpush-server/pull/275), could you please review? Thanks!
