I have a java project in Intellij and use Hg/Mercurial for version control. I ignored some files with this .hgignore file
syntax: glob
target/*
.idea/*
*.iml
and deleted all these files which was committed before. but now I can't execute my project, cause it can not find the file misc.xml.
What should I do?
At first, you shouldn't really ignore everything under .idea but instead only .idea/workspace.xml and .idea/tasks.xml, as it JetBrains states: http://devnet.jetbrains.com/docs/DOC-1186
To solve your problem and get your project back to working state there are possibly two solutions:
Checkout the last commit that contains the files under .idea folder with
hg checkout SHA,
where SHA is the commit id.
After that reset your working space to the head:
hg reset HEAD
Edit your .hgignore in the way that was recommended before, add project files to stage, and commit them:
hg commit -am "Reverted project settings"
If there is no commit with the project settings, you can just import your code back. Start Intellij IDEA and choose "Import Project". Choose the folder with your code, and choose the appropriate SDK after.
