Run same jar file sequentially in a loop for different inputs

Am executing a jar file in remote server using jenkins job build step through publish over ssh.
Input build parameters for the job,say list - a,b,c,d,e
Execution command for publish over ssh -
cd /myjarfilepath
for input in $list
do
java -Xmx1024m -cp myApp.jar com.CommandLineRunner $input
done
job fails with error
ERROR: Exception when publishing, exception message [Exec timed out or was interrupted after 120,000 ms]
It runs successfully for one input. Say if it fails for input b then it gets terminated without executing the jar for c,d,e. I want execute the jar for all the inputs available.
Any suggestions will be appreciated!
Thanks.

Yes this is because of default timeout set to=120000. By updating transfers->Advanced->Exec Timeout(ms). I was able to build for all in loop successfully.

Is there anyway to auto-run a file in Universal Gcode Sender on the program's startup instead of having to upload a file?

I have a file "myFile.gcode" which contains some G-code commands. As it stands Universal Gcode Sender allows the user to upload a file to be executed. However I would like "myFile.gcode" to be run as soon as the program starts up instead of me having to upload it.
Is this possible with the out-of-the-box .jar file?
.jar available at https://winder.github.io/ugs_website/
If not I have the following idea,
Trace through the code and reverse engineer it to auto run the file. To do this I decompiled the .jar file, but when tracing through the code I'm having trouble finding the starting point (main class) of the code.
In summary, is this possible?
And, what could make tracing this code easier?

Yes there is a new feature for running CLI-commands, download the latest nightly build of Universal G-code Sender Classic and run the follwing:
# java -cp UniversalGcodeSender.jar com.willwinder.ugs.cli.TerminalClient --help
This will print the available parameters and options:
-b,--baud <baudrate> Baud rate to connect with.
-c,--controller <controller> What type of controller firmware we are
connecting to, defaults to "GRBL". These
are the available firmwares: [GRBL, TinyG,
Testing (Delay), Smoothie Board, Testing]
-d,--daemon Starts in daemon mode providing a web
pendant UI
-dr,--driver <driver> Sets and saves the connection driver
setting. These are the available drivers:
[JSERIALCOMM, JSSC, TCP]
-f,--file <filename> Opens a file for streaming to controller
and will exit upon completion.
-h,--help Prints the help information.
-ho,--home If a homing process should be done before
any gcode files are sent to the
controller.
-l,--list Lists all available ports.
-p,--port <port> Which port for the controller to connect
to. I.e /dev/ttyUSB0 (on Unix-like systems
or COM4 (on windows).
-pp,--print-progressbar Prints the progress of the file stream
-ps,--print-stream Prints the streamed lines to console
-r,--reset-alarm Resets any alarm
-v,--version Prints the software version.
-w,--workspace <dir> Sets and saves the workspace directory
setting
Sending a file can be done using the following command:
# java -cp UniversalGcodeSender.jar com.willwinder.ugs.cli.TerminalClient --controller GRBL --port /dev/ttyUSB0 --baud 115200 --print-progressbar --file test.gcode
Connected to "Grbl 0.9z" on baud 115200
Running file "test.gcode"
test.gcode 52% │██████████████████████▉ │ 55/105 (0:00:06 / 0:00:05)

schtasks : ERROR: Incorrect Start Date

I am using "schtasks" to create a task in the windows task Scheduler. Below is the command that am using.
"SchTasks /Create /TN CRM_TELESMART_ICE /TR "perl D:\Serviont\LSS-Phase2\hdfc_Perl\bin\common_processing.pl --sourcename CRM_TELESMART_ICE --type DB" /SD 06/23/2016 /ST 12:38 /SC MINUTE /MO 20 /F "
Here the problem is, when I run this java file it executes well and creates a task in local machine. In server it is showing the below error.
Process exiting with code: -2147467259
ERROR: Incorrect Start Date.
I tried to create the same via a standalone java application it is working in server too. The only problem is, when calling through the production application.
Can someone help me on this ?

Old question I know but have you tried using a sensible date such as 23/06/2016? Possibly the regional settings in your Java file are set to something other than American somehow.

Running Single instance AppScale in a virtual machine

I was trying to run AppScale in a Single-instance node installed in a Vmware box and running the appscale-tools in the same server virtual machine and got this error:
root#appscale:~appscale-tools-bin# ./appscale-run-instances --ips ips.yaml
About to start AppScale over a non-cloud environment.
Head node successfully created at 127.0.0.1. It is now starting up cassandra via the command line arguments given.
Generating certificate and private key
Starting server at 127.0.0.1
Please wait for the controller to finish pre-processing tasks.
Warning: Permanently added '127.0.0.1' (RSA) t othe list of known host.
Error: Couldn't find me in the node map
The solution I was advised was to change a code in this source:
appscale/AppController/lib/helperfunctions.rb
And look for self.local_ip() and change to:
def self.local_ip()
return "127.0.0.1"
end
But when I run
./appscale-run-instances --ips ips.yaml
I am not sure, but it just keep on saying:
"Please wait for the controller to finish pre-processing tasks." for several minutes already.
So I decided to terminate it, and here is what I get:
"...common_functions.rb:399:in 'sleep_unti_port_is_open"
In this case, it seems I need to open a port, I am running AppScale from within Ubuntu, what port should I open in my server?
Here's the complete command line:
./appscale-run-instances --ips ips.yaml

Using the pre-build Appscale images here or following the steps listed here https://github.com/AppScale/appscale/wiki/Virtualized-Cluster will solve this problem.
Also it has the build script:
$ sudo su
# cd /root
# wget -O - http://bootstrap.appscale.com | sh

Can't run play app on os x lion

I created an alias like this alias play=/Users/bobdylan/Documents/play/play
After creating a new app and trying to run it with play run I keep getting this:
Debugger failed to attach: handshake failed - received >GET / HTTP/1.1< - excepted >JDWP-Handshake<
Debugger failed to attach: handshake failed - received >GET / HTTP/1.1< - excepted >JDWP-Handshake<
Any idea what could be wrong?

That shouldn't prevent your application from starting, only the debugger from being acceessible. It should also show an exception stacktrace which may help us to point the issue (if it's showing in your case please attach it).
To solve the issue, can you check:
Ports you are using for Play (maybe you have some other server blocking those ports)
The hostname of your computer (you may have localhost pointing somewhere in your host file or some configuration that makes Play fail)

JPDA_PORT is set in the play script so you could either edit the play script in the install or you could export it before running play
export JPDA_PORT=8888
In the play script change
if test "$1" = "debug"; then
JPDA_PORT="9009"
shift
