从Jenkins运行时"latest.integration“的常春藤解析失败

Question

因此，我有一个现有的ant构建，我想使用Ivy来解决它的依赖关系。我有一个ivy.xml和ivysettings.xml文件，这两个文件都可以在Eclipse中使用IvyDE，也可以在命令行对ivy-2.3.0.jar运行时工作。(它们的工作方式与常春藤报告中下载的依赖项一样)。

我遇到的问题是，当'rev‘属性被列为'latest.integration’时，它们在从任何构建脚本运行时都不能工作。如果我指定了一个版本，那么依赖项就会被解析。要明确的是，这种特定的依赖关系是由Artifactory托管的内部库。

对于我能改变什么或试图找出问题，我感到相当困惑。当我运行常春藤时，我也会遇到同样的失败。

请注意，Jenkins正在mac上运行，但我可以使用Ivy jar直接使用该机器上相同的常春藤文件来解决依赖关系，这个问题只有在通过Jenkins解析时才会出现。

我意识到，这不太可能是一个人可以直接观察和指出问题的东西，尤其是考虑到在看似所有其他情况下，即使是通过eclipse从ant构建中运行代码片段，解决方案也是正确的。但是，如果有人有任何建议，他们将非常欢迎！

不管怎样，我的ivy.xml

<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="MyOrg"
        module="MyModule"
        status="integration">
    </info>

    <dependencies>
        <dependency org="MyOrg" name="DEP" rev="latest.integration">
            <artifact name="DEP" type="jar" ext="jar" />
        </dependency>
        <dependency org="junit" name="junit" rev="4.8.1" />
    </dependencies>
</ivy-module>

和我的ivysettings.xml (依赖项命名为DEP-0.1-SNAPSHOT.jar)

<?xml version="1.0" encoding="UTF-8"?>
<ivy-settings>
  <settings defaultResolver="snapshot" />
  <!--Authentication required for publishing (deployment). 'Artifactory Realm' is the realm used by Artifactory so don't change it.-->
  <credentials host="HOST" realm="Artifactory Realm" username="USR" passwd="PASS" />
  <resolvers>
    <chain name="main">
      <!-- <ibiblio name="release" m2compatible="true" root="http://HOST/artifactory/libs-release" /> -->
      <chain name="snapshot" changingPattern="0.*" checkmodified="true">
        <ibiblio name="public" m2compatible="true" root="http://HOST/artifactory/libs-snapshot" />
      </chain>
    </chain>
  </resolvers>
</ivy-settings>

最后，我的构建脚本看起来就像

<project name="MyModule Continuous Integration" xmlns:ivy="antlib:org.apache.ivy.ant">
....
<target name = "resolveDependencies" >
    <ivy:configure file="/MyModule/ivysettings.xml" />
    <ivy:findrevision organisation="MyOrg" module="DEP" revision="latest.integration" property="found.revision" />
    <echo message="Found revision: ${found.revision}" />
    <ivy:resolve file="/MyModule/ivy.xml" refresh="true" type="jar" />
    <ivy:cachepath pathid="ivy.dependencies" />
</target>
....
</project>

为了完成，我从Jenkins构建中获得的输出是：

[ivy:findrevision] snapshot: Checking cache for: dependency: MyOrg#DEP;latest.integration {}
[ivy:findrevision] don't use cache for MyOrg#DEP;latest.integration: checkModified=true

再次感谢你的建议，

作为将来的参考，我已经设法通过交换到最新的Ivy 2.4 alpha构建来解决这个问题。看来这一定是2.3.0的问题。
