在Ivy中找到隐藏的依赖项 [英] Find hidden dependencies in Ivy

问题描述

我正在使用Apache Ivy + IvyDE来获取项目的依赖项，它们是：

I'm using Apache Ivy + IvyDE for getting my project's dependencies, which are:

    <dependency org="com.google.guava" name="guava" rev="r08" />

    <!-- logging -->
    <dependency org="org.slf4j" name="jcl-over-slf4j" rev="1.6.1" />
    <dependency org="ch.qos.logback" name="logback-classic" rev="0.9.27" />

    <!-- database -->
    <dependency org="org.hibernate" name="hibernate-entitymanager" rev="3.6.2.Final" />
    <dependency org="org.hibernate" name="hibernate-validator" rev="4.1.0.Final" />
    <dependency org="org.hibernate" name="hibernate-c3p0" rev="3.6.2.Final" />
    <dependency org="mysql" name="mysql-connector-java" rev="5.1.14" />

来源是Maven和JBoss（Hibernate）存储库。

Sources are the Maven and JBoss (Hibernate) repositories.

正如你所看到的，我正在使用logback + SLF4J进行日志记录，但由于某种原因，Ivy也会下载log4j和slf4j-log4j，这会在我的应用程序中引起一些小问题。

As you can see I'm using logback+SLF4J for logging, but for some reason Ivy will download log4j and slf4j-log4j as well, which causes a few small problem in my application.

有没有办法看到为什么会发生这种情况，看看上面哪些依赖项依赖于log4j？我可以获得从Ivy / IvyDE生成的依赖图/树吗？

Is there a way to see why this happens, to see which of the dependencies above depend on log4j? Can I get a dependency graph/tree generated from Ivy/IvyDE?

那么有没有办法防止这种情况发生？

And is there then a way to prevent this from happening?

推荐答案

我们有一个蚂蚁目标，如下所示：

We have an ant target that looks like this:

<target name="report" depends="init">
    <mkdir dir="report" />
    <!-- 
     The type attribute is optional, we're using it to exlude other dependcy types we're not interested in. 
     Note that each resolve uses that list (via a property) in our build. 
    -->
    <ivy:resolve type="jar,ejb,tld,bundle"/> 
    <ivy:report todir="report" />
</target>

然后它只是一个电话蚂蚁报告和Ivy将在给定目录中以HTML格式生成报告。

Then it's just a call ant report and Ivy will generate the report as HTML in the given directory.

编辑：

为防止包含这些工件/依赖项，您可以在上尝试 transitive =false < dependency ...> 元素，或使用< exclude> 。例如，我们使用Hibernate 3但不想拥有 JTA 1.1 ，所以我们的 ivy.xml 包含这个：< exclude module =jta/> 以排除所有可传递的JTA依赖项。

To prevent the inclusion of those artifacts/dependencies, you could try transitive="false" on the <dependency ..> element, or use <exclude>. For example, we use Hibernate 3 but don't want to have JTA 1.1, so our ivy.xml containts this: <exclude module="jta"/> to exclude all transitive JTA dependencies.
