Existe uma maneira de configurar o ivy para não baixar fontes e arquivos de licença via ivy.xml?

Atualmente, estou tentando usar o repositório padrão do ivy repos + spring. meu ivysettings.xml está abaixo:

<?xml version="1.0" encoding="ISO-8859-1"?>

<settings defaultResolver="springSource" />
<include url="${ivy.default.settings.dir}/ivysettings-public.xml" />
<include url="${ivy.default.settings.dir}/ivysettings-shared.xml" />
<include url="${ivy.default.settings.dir}/ivysettings-local.xml" />
<include url="${ivy.default.settings.dir}/ivysettings-main-chain.xml" />
<include url="${ivy.default.settings.dir}/ivysettings-default-chain.xml" />
<resolvers>
    <chain name="springSource">
        <url name="com.springsource.repository.bundles.release">
            <ivy
                pattern="http://repository.springsource.com/ivy/bundles/release/[organisation]/[module]/[revision]/[artifact]-[revision].[ext]" />
            <artifact
                pattern="http://repository.springsource.com/ivy/bundles/release/[organisation]/[module]/[revision]/[artifact]-[revision].[ext]" />
        </url>

        <url name="com.springsource.repository.bundles.external">
            <ivy
                pattern="http://repository.springsource.com/ivy/bundles/external/[organisation]/[module]/[revision]/[artifact]-[revision].[ext]" />
            <artifact
                pattern="http://repository.springsource.com/ivy/bundles/external/[organisation]/[module]/[revision]/[artifact]-[revision].[ext]" />
        </url>

        <ibiblio name="public" m2compatible="true" />
        <ibiblio name="shared" m2compatible="true" />
        <ibiblio name="local" m2compatible="true" />
        <ibiblio name="main-chain" m2compatible="true" />
