java - How to subtract ivy dependency sets -


my goal demarcate project transitive dependencies several not crossing sets:

  • system (jars present in j2ee container; listed manually explicit fixed versions)
  • provided (jars copied j2ee container; listed manually)
  • ear (jars packed inside ear/lib, rest)

my current solution listed below has shortcomings:

  • have exclude system , provided libraries ear conf 1 one
  • new third-party transitive deps weren't explicitly excluded accidentally ear
  • sometimes have add explicit override duplicating library name , version

is there approach possible eliminate these shortcomings?

it nice able somehow define 1 conf result of dependency sets subtraction of others (with graceful conflict resolution): ear = runtime - system - provided.

maybe <conf name="ear" extends="runtime,!system,!provided"/> notation supported when ivy-982 gets fixed.

looking actual solution apply.

even willing consider switching gradle if has solution.

<?xml version="1.0" encoding="utf-8"?> <ivy-module version="2.0" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"             xsi:nonamespaceschemalocation="http://ant.apache.org/ivy/schemas/ivy.xsd">      <info organisation="example.com" module="parent"/>      <configurations defaultconfmapping="compile->@;runtime->@;system->master;provided->runtime;ear->runtime;test->test(default)">         <conf name="compile"/>         <conf name="runtime" extends="compile"/>         <conf name="ear" extends="runtime" description="libs packed inside ear"/>         <conf name="provided" description="libs copy j2ee container"/>         <conf name="system" description="libs present in j2ee container"/>         <conf name="test" extends="ear,provided,system" description="simulate container environment. used unit tests catch dependency compatibility problems."/>     </configurations>      <dependencies>         <dependency org="log4j" name="log4j" rev="1.2.15" force="true" conf="system"/>         <dependency org="commons-collections" name="commons-collections" rev="3.1" force="true" conf="system"/>         <dependency org="commons-lang" name="commons-lang" rev="2.2" force="true" conf="system"/>          <dependency org="org.apache.velocity" name="velocity" rev="1.7" force="true" conf="provided"/>         <dependency org="org.slf4j" name="slf4j-api" rev="1.5.6" force="true" conf="provided"/>         <dependency org="org.slf4j" name="slf4j-log4j12" rev="1.5.6" force="true" conf="provided"/>         <!-- ... -->          <dependency name="module1" rev="latest.integration" conf="runtime,ear,provided,test"/>         <dependency name="module2" rev="latest.integration" conf="runtime,ear,provided,test"/>         <!-- ... -->          <exclude org="commons-collections" conf="ear,provided"/>         <exclude org="commons-lang" conf="ear,provided"/>         <exclude org="org.apache.velocity" conf="ear"/>         <!-- todo: negation not working: https://issues.apache.org/jira/browse/ivy-982 -->         <!--<exclude org="org.slf4j" conf="*, !provided"/>-->         <exclude org="org.slf4j" conf="ear,test"/>         <!-- ... -->          <override org="org.slf4j" rev="1.5.6"/>         <override org="commons-collections" module="commons-collections" rev="3.1"/>         <override org="commons-lang" module="commons-lang" rev="2.2"/>         <!-- ... -->     </dependencies>  </ivy-module>

sample project sources experiment can found in ivy-1443 attachment.

while provided dependencies exclusion possible maven , gradle, seems there no way achieve ivy.

update

in cases task can worked around intermediate induced module , negative regexp mask:

    <dependency org="com.company" name="root.module" conf="ear" rev="latest.integration">         <exclude org="^(?!com.company).*$" matcher="regexp"/>     </dependency>

but we've moved gradle ivy seems losing momentum.
