Here is what you can try.
You can use the command -DconfigFile=<your file> : such as
ant updatesystem -Dtenant=<my tenant> -DconfigFile=path/to/my/config.json
And here is an example of the config.json
{
"init": "Go",
"initmethod": "update",
"clearhmc": "true",
"essential": "true",
"localizetypes": "true",
"solrfacetsearch_sample": "true",
"hmc_sample": "true",
"solrfacetsearchhmc_sample": "true",
"customerreview_sample": "true",
"voucher_sample": "true",
"promotions_sample": "true",
"basecommerce_sample": "true",

"payment_sample": "true",

"yacceleratorcore_sample": "true",
....
"electronicsstore_importCoreData": [
"yes"
],
"electronicsstore_importSampleData": [
"yes"
],
"electronicsstore_activateSolrCronJobs": [
"yes"
],
"yacceleratortest_createTestData": [
"yes"
],
"yacceleratorcockpits_importCustomReports": [
"yes"
]
}
As you can see it's not so easy to implement this file, as suggested in, Initializing and Updating SAP Hybris Commerce, go to the HAC once, do you configuration in the webpage and click on Dump configuration. It will give you the generated json file.
I hope the above information would be helpful for you.
