Question

我试图将Apache Ivy与使用Apache Ant的现有Java EE项目集成。我创建了ivy.xml，ivysettings.xml（在mvnrepo中添加了一个不存在的repo）并对现有的build.xml进行了更改。

当我运行Ivy Resolve时，我得到了以下内容：

[ivy:resolve] :: resolution report :: resolve 2642ms :: artifacts dl 49ms
[ivy:resolve]   :: evicted modules:
[ivy:resolve]   xml-apis#xml-apis;1.0.b2 by [xml-apis#xml-apis;1.3.04] in [default]
[ivy:resolve]   commons-logging#commons-logging;1.1.1 by [commons-logging#commons-logging;1.2] in [default]
[ivy:resolve]   commons-codec#commons-codec;1.6 by [commons-codec#commons-codec;1.8] in [default]
[ivy:resolve]   commons-logging#commons-logging;1.1.3 by [commons-logging#commons-logging;1.2] in [default]
[ivy:resolve]   org.slf4j#slf4j-api;1.6.1 by [org.slf4j#slf4j-api;1.7.7] in [default]
[ivy:resolve]   xml-apis#xml-apis;1.3.04 by [xml-apis#xml-apis;1.4.01] in [default]
    ---------------------------------------------------------------------
    |                  |            modules            ||   artifacts   |
    |       conf       | number| search|dwnlded|evicted|| number|dwnlded|
    ---------------------------------------------------------------------
    |      default     |  108  |   0   |   0   |   6   ||  102  |   0   |
    ---------------------------------------------------------------------

如何解决此问题？ ivy.xml中没有直接提到这些模块。这是我对常春藤的第一次实验，任何帮助都将受到高度赞赏。

ivysettings.xml

<ivysettings>
    <settings defaultResolver="central"/>
    <resolvers>
        <ibiblio name="central" m2compatible="true"/>
        <ibiblio name="primefaces-themes-old" m2compatible="true" root="http://repository.primefaces.org"/>
    </resolvers>
    <modules>
        <module organisation="org.primefaces.themes" resolver="primefaces-themes-old"/>
    </modules>
</ivysettings>

Answer 1

如果在关闭依赖项标记之前添加行<conflict manager="all"/>，则表示您不会拥有任何已驱逐的模块。像这样

    <conflict manager="all"/>
</dependencies>

从here引用内置冲突管理器all：

此冲突管理器通过选择所有修订来解决冲突。也称为NoConflictManager，它不会驱逐任何模块。

我必须把conflict放在最后，否则它不会起作用。好像是a bug in ivy。

请确保这是您想要的。引自here：

在解决冲突期间优化了两件事：下载工件和常春藤文件的下载。第一个始终是由常春藤，即被驱逐模块的文物永远不会被下载。该第二个不是那么简单，因为知道是什么冲突常春藤需要知道依赖图，并知道依赖图，它必须下载常春藤文件。但是常春藤很高兴对此进行了优化，并试图尽快驱逐模块可能。这就是为什么依赖关系的顺序很重要的原因下载优化。事实上，常春藤遍历依赖图依赖项在常春藤文件中声明的顺序，以及每次遇到对模块的依赖时，首先检查是否这个模块存在冲突，如果是这种情况，它会问冲突经理解决冲突。然后，如果模块是被驱逐，它不下载它的常春藤文件，整个分支是没有经过，这可以节省很多时间。

Answer 2

只需添加一些内容即可。

冲突部分工作正常。

<conflict manager="all"/>

无论如何，要找到有关它的信息并不容易，知道它的用法可以限制为单个依赖项，或者还使用通配符来选择它们的子集可能会很有用。就我而言，我是这样使用的：

<conflict manager="all" module="module_1" org="org_1"/>

此外，还可以选择使用不同的经理选择不同的策略，有关更多信息，请访问：http://ant.apache.org/ivy/history/2.0.0/settings/conflict-managers.html
