Cannot run install.app on Mac OSX 10.10.5

[An Nguyễn]

Hi all, I'm trying to setup enviroment to work with iDempiere 2.1 on my macbook. My env is:

- Mac OSX 10.10.5

- Eclipse Mars 4.5.0

- iDempiere 2.1

- Buckminster - Core 1.7.0.v20150718-2211

- Java SE-1.6 [1.6.0_65] / Java SE-17. [1.7.0_75] / Java SE-1.8 [1.8.0_60]

When after importing and materializing projects, I try to run install.app with the default settings for Execution environment is Java SE-1.6, and there's an error:

java.lang.UnsupportedClassVersionError: org/compiere/util/CLogFile : Unsupported major.minor version 51.0

Previously I used compiler 1.7 as default Eclipse's compiler. Thought it is the problem, I tried to change Java compiler to 1.6, also change the specific settings for org.adempiere.install project, but the error still happens.

Then I tried to change Execution environment of install.app to Java SE-1.7, but with that settings the console was totally empty, nothing happens.

Can anyone please give me some advices?

Thank you very much.

Try Clean All and Build projects. Also check thoroughly in Preferences and properties default to see 1.6 works.

Try on Eclipse Preferences ->> Plug-in Development --> target Platform.

Select Target Platform that you created, an then on Enviroment Tab, 

Normally you leave empty Values for Variables.

I put Asterisk ('*') on Operating System, Windowing System and Architecture.

It works fine for me on Eclipse LUNA.

I hope this help you

Hi, thank you all for supporting~

I tried to change "-arch ${target.arch}" to "-arch x86" as an article I found on the Internet and it works now. They said it's a known issue of swing on Mac OS. I'm not very clear, however it works..
