如何在Apache Ivy中使用TestNG？

Question

I tried to use TestNG with Apache Ivy , but was unsuccessful. Here is my ivy.xml :

<ivy-module version="2.0">

    <info organisation="me" module="myproject"/>

    <dependencies>
      <dependency org="org.testng" name="testng" rev="5.8" />
    </dependencies>

</ivy-module>

This fails to actually download a TestNG jarfile. It seems to be because TestNG has a jarfile for jdk14 and jdk15. Here's the output from ivy:retrieve :

[ivy:retrieve] :: resolving dependencies :: me#myproject;working@jared-mbp17

In the repository you can see two different jarfiles: http://repo1.maven.org/maven2/org/testng/testng/5.8/testng-5.8-jdk14.jar http://repo1.maven.org/maven2/org/testng/testng/5.8/testng-5.8-jdk15.jar

How do I specify either jdk14 or jdk15 ?

Answer 1

You need to specify the classifier of the artifact you want.

There is a related fix as of 2.1.0-RC1 . You can use the element artifact within the dependency element to specify the classifier you want. In this case, the classifier should be jdk14 or jdk15 . If you want jdk15 your ivy.xml would then be:

<ivy-module version="2.0"
            xmlns:e="http://ant.apache.org/ivy/extra">

    <info organisation="me" module="myproject"/>

    <dependencies>
      <dependency org="org.testng" name="testng" rev="5.8"
                  transitive="false">
        <artifact name="testng" type="jar" ext="jar" e:classifier="jdk15" />
      </dependency>
    </dependencies>

</ivy-module>

Note the specification of the XML namespace "http://ant.apache.org/ivy/extra" as an attribute of the ivy-module element. Without that the e:classifier won't work.
