Version control ignore list for google app engine Java apps

Question

Is there a standard list of files/directories/pattens that can be added to a version control ignore list (e.g. .hgignore) when version controlling the source of a Google app engine Java app?

I guess a bunch of people must have worked this out already, any good examples out there?

Answer 1

Standard list, maybe not, but you have some examples:

syntax: regexp

\.*py[co]
\.DS_Store
~$
\.coverage
\.egg-info

syntax: glob

nbproject
app.yaml
auth.py
dist
target
WEB-INF/appengine-generated

Basically, at least any directory with generated content should be ignored.

The same principles holds true for Java app projects like this one or that one:

syntax: glob

*~
*.patch
*.sedbak
*/target/*
*/<project_name>searchindex/*
*/test-output/*

hs_err_pid*.log
tomcat

syntax: regexp
\.jar$

^\.pc/
^.ant-targets-build.xml
\.pages.xml.spdia$
temp-testng-customsuite.xml$

# eclipse and maven stuff
^target

# kde related
\.directory$

#gwt related
^<project_name>-war/war/WEB-INF/classes/
^<project_name>-war/tomcat
\.gwt-tmp$
^<project_name>-war/org.fedorahosted.<project_name>.webtrans.Application
^<project_name>-war/war/org.fedorahosted.<project_name>.webtrans.Application

Off course, I will keep any Eclipse or maven related file under source control, in order to facilitate the build step when anyone will clone the repo.

Answer 2

I use the maven-gae-plugin and develop within eclipse. This .hgignore I often copy in new projects:

\.project
\.classpath
\.settings/
^target$

Besides that, you need to consider something else: When you deploy an appengine application, the appengine sdk runtime sends a relation of files to be published along with their checksums, and only updated files are uploaded.

Answer 3

Well, with a lack of any obvious answers, I made my own up. Here's the .hgignore I went with, replacing [app-name-here] with the name of the app:

syntax: glob
*.class
war/[app-name-here]
war/WEB-INF/classes

The repo is public if anyone is interested.
