ant - Using a configuration intersection in ivy -

-

i thankful help.

we use ant\ivy manage our dependencies. , want download minimum quantity of modules: needed build. try use configuration intersection, got not expecting ivy behavior.

https://ant.apache.org/ivy/history/latest-milestone/ivyfile/dependency.html

since 2.1 possible define dependencies on configurations intersection. configuration intersection defined using '+' sign separate configuration (eg 'a+b' means intersection of configuration 'a' , 'b'). in case artifacts , dependencies defined in both configurations in dependency part of master configuration defining dependency on configuration intersection.

configuration intersections can used when specifying confs resolve.

build.xml file:

<project xmlns:ivy="antlib:org.apache.ivy.ant" xmlns:e="http://ant.apache.org/ivy/extra" name="test" default="get">     <target name="get" description="-->downloads artifacts , prepare it">         <ivy:resolve file="ivy.xml" conf="${conf}" />     </target> </project>

ivy file:

<?xml version="1.0" encoding="utf-8"?> <ivy-module version="2.0" xmlns:e="http://ant.apache.org/ivy/extra">     <info module="test" organisation="main" revision="1.0"/>     <configurations>         <conf name="release"        e:axis="download_type" />         <conf name="dev"            e:axis="download_type" />          <conf name="client"         e:axis="product"/>         <conf name="server"         e:axis="product"/>     </configurations>      <dependencies>         <dependency org="main" name="zlib" branch="trunk" rev="1.2.8.+" conf="dev->*;client->*"/>     </dependencies> </ivy-module>

case 1:

ant -dconf="dev+server"

case 2:

ant -dconf="server+dev"

i expect results same in first , second case: zlib shouldn't downloaded, because intersection of "dev" , "server" confs nothing. get:

  • in case 1: zlib not dowloaded
  • in case 2: zlib dowloaded

where misunderstanding?

thanks

ps. version of ivy 2.4.0

java - UML - How would you draw a try catch in a sequence diagram? -

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
