常春藤conf斗争

Question

I am currently struggling with apache ivy's conf settings. Maybe i'll explain what i want to achieve first:

1. I want two configurations: compile, runtime
2. I want for each configuration that ivy resolves, all jars including the transitive dependencies

Here's something i tried:

<configurations>
    <conf name="compile" visibility="public"/>
    <conf name="runtime" visibility="public" extends="compile"/>
</configurations>
<dependencies>
    <dependency org="org.apache.ivy" name="ivy" rev="2.4.0" conf="runtime->runtime, compile->compile"/>
</dependencies>  

But it cannot even be parsed: The ivy file '...\\ivy.xml' could not be parsed:

Could please someone tell me how to declare the conf settings properly, so that i can resolve using either compile or runtime and get all jars including the transitive dependencies(in the example case only the jars of ivy).

Update

Ok, thanks for the links. This makes it a bit clearer, but i'm still stuck.

I changed the dependency declaration so that it resolves the ivy jars in scope 'default': (I left out the "compile->default" declaration, as it seems there's a bug in the parsing of ivy eclipse plugin)

<dependency org="org.apache.ivy" name="ivy" rev="2.4.0" conf="runtime->default"/>

and retrieved the jars (using the ivy eclipse plugin) with the settings confs='*' and types='*' .

All i got was a single ivy-2.4.0.jar. I expected all runtime dependencies. I can't exactly tell which they are, as i don't understand the declarations in ivy's xml file like(the whole xml file is appended later):

<dependency org="org.apache.ant" name="ant" rev="1.7.1" force="true" conf="optional->compile(*),master(*)"/>

Here's how i understand the conf="runtime->default" declaration:

• The ivy dependency is assigned to (local) conf 'runtime'
• The ivy dependency is assigned to remote conf 'default'

• Whenever i resolve (or retrieve) the dependency for conf 'runtime' i get all of the remote dependencies including the transitive dependencies for conf 'default', as the 'default' conf is declared as

  "The remote module's artifact and all it's runtime transitive dependencies" link

Here's my ivy.xml:

Answer 1

Sounds like an XML formatting problem.

The following examples demonstrate how ivy configurations can be used to manage separate "compile", "runtime" and "test" classpaths:

• Ivy, what is the master configuration and why is it not pulling jvyaml?
• Class not found with Ant, Ivy and JUnit - error in build.xml?
