java.lang.IllegalAccessError when I click on "Add to .gitignore file"

[lopotun]

So, when I right-click on a file in project and call "Add to .gitignore file" menu item, I get the error mentioned below. It happens on Windows7, IntelliJ 12.1.6, plugin version: 1.1.4.

As I can see, mobi.hsz.idea.gitignore.actions.IgnoreFileAction tries to call com.intellij.openapi.util.text.StringUtil.escapeChar(String, char) method while this method is private (see http://grepcode.com/file/repository.grepcode.com/java/ext/com.jetbrains/intellij-idea/12.1.2/com/intellij/openapi/util/text/StringUtil.java#StringUtil.escapeChar%28java.lang.String%2Cchar%29 )

@lopotun Thank you for reporting. Indeed - this method was private in the IntelliJ 12.x - since I'm working with later API it didn't report me any issues. Anyway - I've made a fix for that and it'll be pushed in the next release of the plugin.

@hsz Thank you for your prompt responce! :-)
Do you succeed to compile the project? I don't. For example mobi.hsz.idea.gitignore.util.CacheMap uses mobi.hsz.idea.gitignore.psi.IgnoreEntry and mobi.hsz.idea.gitignore.psi.IgnoreVisitor that don't exist in the project.
Thanks.

@lopotun It looks like you didn't generate sources from BNF and Flex files.

Have you read Compiling the source code in README ?

[lopotun]

@hsz Oh, sorry! That's my fault. I'll do it according to instructions. Thanks!

@hsz Well, it seems we're about to move to IDEA 14.X next week, so this won't be relevant anymore for me.
For those who still want/need to compile the plugin in IDEA 12.X there are some notes that arn't covered by README.md:

1. There is no "Resources" configuration section in IDEA 12.X.
2. JFlex plugin's configuration points to ".../JetBrains/IntelliJ IDEA 12.1.4/tools/jflex" directory that actually does not exist (IDEA 12.X problem? JFlex plugin's problem?).
3. When you run "JFlex Generator" IDEA 12.X fails to download some file fron GitHub.com due to untrusted certificate issue. There are chances, however, that this is our local problem since we're behind strict corporate firewall.
