Should i build BioMart on Eclipse IDE?

[Seong-ho Cho]

I'm a system manager of Biocon, where is next-generation organization of i-Pharm, Republic of Korea.

old members are gone for founding their new company, and making their own business.

I'm trying to recover our BioMart system by executing 

# ant

from a root folder of the BioMart source tree.

because I have met an error like below from one half years ago,

ERROR: Compilation error

I tried two or more times with change version to 1.7 from 1.6 in build.xml.

jdk compiler version is 1.7.0_141.

I didn't eliminate this situation, of course I have seen little-bit-thick(?) manual lastly published in May, 2014.

I found there is some hints about using Eclipse IDE.

so, my simple question is 

"Should I build BioMart on Eclise IDE to make working app?"

I know this source tree is too old since It wrote and I believe there is some way to recover to work.

Thank you in advance.

Cho.
