如何在Apache Ivy上使用TestNG？

Question

我试图使用TestNG和Apache Ivy，但没有成功。这是我的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> 

这实际上没有下载TestNG jarfile。这似乎是因为TestNG为jdk14和jdk15提供了一个jar文件。下面是从ivy:retrieve输出：

[ivy:retrieve] :: resolving dependencies :: me#myproject;working@jared-mbp17 
[ivy:retrieve] confs: [default] 
[ivy:retrieve] found org.testng#testng;5.8 in public

在库中，您可以看到两个不同的jarfiles中： 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

如何指定要么jdk14或jdk15？

Answer 1

您需要指定所需工件的分类器。

有一个相关的fix as of 2.1.0-RC1。您可以使用dependency元素中的元素artifact来指定所需的classifier。在这种情况下，分类器应该是jdk14或jdk15。如果你想你的jdk15然后ivy.xml是：

<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> 

注为ivy-module元素的属性的XML命名空间"http://ant.apache.org/ivy/extra"的规范。没有这个e:classifier将无法​​正常工作。
