如何修复Apache Ivy中被驱逐的模块问题

Question

我试图将Apache Ivy与现有的使用Apache Ant的Java EE项目集成在一起。我创建了ivy.xml、ivysettings.xml(在mvnrepo中添加一个不存在的repo)并对现有的build.xml进行了更改。

当我运行常春藤决议时，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|

    ---------------------------------------------------------------------

如何解决此问题？这些模块在常春藤.xml中没有直接提及。这是我对常春藤的第一次实验，任何帮助将不胜感激。

Answer 1

只是为了添加一些东西。

冲突部分工作得很好。

<conflict manager="all"/>

无论如何，要找到有关它的信息并不容易，知道它的使用可以限制为单个依赖项，或者还可以使用通配符来选择其中的一个子集，这可能很有用。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经理的不同策略，更多信息请访问：http://ant.apache.org/ivy/history/2.0.0/settings/conflict-managers.html

Answer 2

如果添加该行

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

从这里引用内置冲突管理器的全部内容：

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

我不得不把冲突放在最后，否则它就行不通了。看起来像常春藤中的一只虫子。

只要确定这是你想要的。从这里引用:

在冲突解决过程中有两件事情得到了优化：工件下载和常春藤文件下载。第一个总是由常春藤保证的，即被收回的模块的工件永远不会被下载。第二种方法处理起来并不简单，因为要知道冲突是什么，ivy需要知道依赖关系图，要知道依赖关系，它必须下载ivy文件。但常春藤在这方面也进行了高度优化，它试图尽快淘汰模块。这就是为什么依赖关系的顺序对于下载优化很重要的原因。实际上，ivy会按照在ivy文件中声明依赖项的顺序遍历依赖关系图，每次遇到模块上的依赖项时，它都会首先检查此模块上是否存在冲突，如果是这样，它会要求冲突管理器解决冲突。然后，如果模块被收回，它不会下载其ivy文件，也不会遍历整个分支，这可以节省大量时间。
