I can set ANT_OPTS to be -Dorg.apache.jasper.compiler.Parser.STRICT_QUOTE_ESCAPING=false and it works correctly. However, I want a setting I can put into the build.xml, so I don't need to tell my teammates that they need to set ANT_OPTS. I've tried <property name="env.org.apache.jasper.compiler.Parser.STRICT_QUOTE_ESCAPING" value="false"/> but that doesn't seem to work. How can I pass an environment variable to

For CPU intensive tasks it's an obvious choice to do it this way, but what about for simply saving data? Is it faster on average to perform a taskqueue.add() operation or a db.put() operation, or is it about the same? 回答1: Yes, marginally. Task queue payloads are limited to 10kb, though, and the performance difference is small enough you shouldn't use a task queue task just to store a

So If A is followed then Task S2 and F2 is executed. But if path B is followed, task F1 and F3 is executed. But also after completing task F3, the flow should go to task S2 via path E. But this doesn't happen and as the task F3 is completed, the package ends with success. I need help on this on how to move to path E and execute task S2 and F2 after task F3 completion. Thanks. 回答1: Your problem is

Why won't this work, what concepts am I missing? 回答1: You just need to use double quotes. Also, drop the << and use doFirst instead if you are planning to do the deletion during execution. Something

I'm thinking of using Spring batch Chunks with reader, processor and writer. My reader will return one item at a time from the list and sends it to processor and once processing is over, it returns to Writer where it updates the DB I may be multithreading it later with some cost of synchronization in these methods. Here I foresee a few concerns. Number of items to be processed

It could happen that two or even more Scripts are being selected in a timespan of two or three seconds. The Goal is to have a Scheduler which collects all the tasks and executes them one after the other. A FIFO functionality should be included. I 've tried the following Code just to try the functionality of the queuedTaskScheduler, but even that doesn't work. QueuedTaskScheduler queueScheduler; private TaskScheduler ts_priority1; int pos = 0; public

In the current example I require a 3D FT for a 1921 x 512 x 512 image (along with 2D FFTs of 512 x 512 images). Right now, I am using the numpy package and the associated function np.fft.fftn() . The code snippet below exemplarily shows 2D and 3D FFT times on an equal-sized/slightly smaller 2D/3D random-number-generated grid in the following way: import sys import numpy as np import time tas = time.time() a = np.random.rand(512, 512) tab = time.time() b =
