Usage of apply plugin: 'application' tag in build.gradle file -


i starting explore gradle , question might naive. have noted gradle docs below plugin-

apply plugin: 'application' application plugin facilitates creating executable jvm application. makes easy start application locally during development. applying application plugin implicitly applies java plugin.

i want understand if below plugin entry mandatory have not seen in many projects. if used make jar runnable/creating executable jvm application. mean skipping not make application executable ?

the 'application' plugin not mandatory when creating executable jvm application, facilitates creation of one.

you can use other plugins create runnable jar, 1 of them shadow plugin

if know how structure of runnable jar should like, can on own , pack needed libraries small apps or testing extending jar task java plugin.

jar { archivename = 'name.jar'  manifest {     attributes 'main-class': 'main',             'class-path': configurations.runtime.files.collect { "lib/$it.name" }.join(' '),             'implementation-version': project.version (if any) }  from(configurations.compile.collect { it.isdirectory() ? : ziptree(it) }) }

i suggest using application plugin. supported, gradle, it's recommended other developers.

applying application plugin implicitly applies java plugin. main source set “application”. , facilitates creation of runnable jar application.

the java plugin adds java compilation along testing , bundling capabilities project. serves basis many of other gradle plugins.

to answer question:

application plugin 1 (recommended) of ways runnable jvm app creation.

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
