java - Ant shortcut for specifying source/version in several different javac tasks -

-

when using ant, there way specify set of attribute/value pairs can passed different tasks single item/variable?

i have ant build file includes several different javac tasks. have same values several attributes (source, version, bootclasspath, debug, etc.)

i know can set variable each attribute; but, there way can refer entire group of attributes can this

<javac ${standard_attributes} ...>

instead of

<javac debug="on" includeantruntime="false" source="${java_version}" target="${java_version}" bootclasspath="${bcp}" ...

in every javac task?

use presetdef

<presetdef name="standard-javac"> <javac debug="on" includeantruntime="false" source="${java_version}" target="${java_version}" bootclasspath="${bcp}" ... </javac> </presetdef>

and use standard-javac task in places used put javac.

i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
