如何找出导致下载特定库的依赖项? [英] How to find out which dependency caused a particular library to be downloaded?

问题描述

运行我的 SBT 项目时，控制台输出中有一行:

When runing my SBT project, there is a line in console output:

[info] downloading http://repository/nexus/content/groups/public/org/jboss/netty/netty/3.2.3.Final/netty-3.2.3.Final.jar ...
[info]  [SUCCESSFUL ] org.jboss.netty#netty;3.2.3.Final!netty.jar(bundle) (651ms)

如何找出是哪个项目依赖导致netty.jar被下载?

How to find out which project dependency caused the netty.jar to be downloaded?

推荐答案

这个插件应该能够帮助:https://github.com/jrudolph/sbt-dependency-graph/

This plugin should be able to help: https://github.com/jrudolph/sbt-dependency-graph/

另一种方法是在您的 build.sbt 中打开完整调试，如下所示:

Another way would be to turn on full debug in your build.sbt as follows:

ivyLoggingLevel := UpdateLogging.Full
logLevel := Level.Debug

然后你可以解析sbt update

例如，如果我想知道示例项目中 logback-core 的来源，我可以运行

For example, If I wanted to know where logback-core comes from in my sample project, I could run

sbt update | grep logback-core

我会得到多条这样的行，告诉我它带有 logback-classic:

And I would get multiple such lines, telling me that it comes with logback-classic:

[debug] == resolving dependencies ch.qos.logback#logback-classic;1.0.10->ch.qos.logback#logback-core;1.0.10 [compile->master(*)]
