added -project parameter for xcodebuild

[amattil1]

When having 2 .xcodeproj files in same directory, xcode plugin fails when xcodebuild command is being executed. This is fixed by passing -project option for xcodebuild command.

Added test for -project parameter.

Any changes to merge the pull request? We would have use for this right away. Using CMake with Xcode, the project will be generated to different folder than where build.gradle resides. xcodeplugin wants the project to exist in same folder which means that cmake needs to generate the build files to same folder as all the other project files, thus writing lot of garbage in the folder and making clean call hard. Also requires lots of svn/git ignore files for cmake temp files. Very messy. With this -project switch I can point the xcodeproj file from subdirectory, and it would all be fine and dandy :) Thanks.

Normally I only merge pull request that are on the develop branch. But I think (and hope) that this changes does not break anything. Lets see.

There is now a 0.22.2 version with your change.

[amattil1]

Awesome, thank you! Seems to work as it should. 👍

Only strange thing is that I cannot directly reference the version 0.22.2, I have to use 0.22.+ in build.gradle. I have maven url https://openbakery.org/repository/ and dependencies defined with classpath group: 'org.openbakery', name: 'xcode-plugin', version: '0.22.2' .. result is "Could not find org.openbakery:xcode-plugin:0.22.2."

Any idea why I need to use + instead of 2?
