如何修复Apache Ivy中的Evicted Modules问题

Question

我正在尝试将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   |
    ---------------------------------------------------------------------

我该如何解决这个问题？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>

的ivy.xml

Answer 1

如果<conflict manager="all"/>在关闭依赖项标记之前添加该行,则不会有任何已逐出的模块.像这样

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

从这里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.

我不得不把它conflict放在最后,否则它将无法工作.好像常春藤里的虫子.

请确保这是你想要的.引自这里:

在解决冲突期间优化了两件事:下载工件和下载常春藤文件.第一个始终由常春藤确保,即永远不会下载被驱逐模块的工件.第二个不是那么简单,因为要知道常春藤需要知道依赖图的冲突是什么,并且要知道依赖图,它必须下载常春藤文件.但是常春藤也在这方面进行了高度优化,它试图尽快驱逐模块.这就是为什么依赖顺序对于下载优化很重要的原因.事实上,ivy按照在常春藤文件中声明依赖关系的顺序遍历依赖图,每次遇到对模块的依赖时,它首先检查此模块是否存在冲突,如果是这种情况,则为要求冲突经理解决冲突.然后,如果模块被驱逐,它不会下载其常春藤文件,并且不会遍历整个分支,这可以节省大量时间.
