How to run bash from arbitrary build tasks in Visual Studio 2017 (directory-based project)? -


i'm trying enable custom build tasks use bash build docbook-based documentation in visual studio 2017. use built-in windows subsystem linux in windows 10. can launch cmd.exe , run dir in ms's examples. however, need run make args in bash , that's fails with:

  '"bash"' not recognized internal or external command,   operable program or batch file.

i can run cmd.exe interactively , start bash without problems. fails in visual studio. vs2017 use special environment? how make run bash via tasks? guess missing simple , trivial, don't understand at.

essentially, want run make all-html command against path docbook sources.

here minimal task example:

{   "version": "0.2.1",   "tasks": [     {       "taskname": "build all-html",       "appliesto": "*",       "type": "command",       "command": "bash"     }   ] }

the reason command doesn't naturally find bash expect because visual studio 32-bit program. means won't use 64-bit cmd.exe when specify commands.

you can reproduce visual studio doing opening 32-bit command window c:\windows\syswow64\cmd.exe , trying bash command there.

the solution invoke bash.exe directly via c:\windows\sysnative virtual folder.

you can find discussion/explanation of sysnative folder , why necessary here in official bash on windows github.

here example command should work you:

{   "taskname": "print-pwd",   "appliesto": "*",   "type": "command",   "command": "%windir%\\sysnative\\bash.exe",   "args": [     "-c",     "pwd"   ] }

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
