sbt - 如何强制特定版本的依赖关系？

Question

依赖项bar取决于foo 1.2.3，但是该foo版本存在错误，我需要使用版本1.2.2。
我可以使用force()做到这一点。

libraryDependencies += "foo" %% "foo" % "1.2.2" force()

docs不推荐该方法:

Forcing a revision (Not recommended)

Note: Forcing can create logical inconsistencies so it’s no longer recommended.

这是否意味着SBT具有比 force()更好的方式来使用特定版本的依赖项？如果是这样，该怎么办？
还是我从文档中推断出整个问题是我不建议的？

Answer 1

您可以使用dependencyOverrides:

dependencyOverrides += "foo" %% "foo" % "1.2.2"

无论如何，您都不会避免“逻辑上的矛盾”。如果强制使用版本，则必须手动注意与其他库的兼容性，这是没有办法的。

从文档中:

Overriding a version

For binary compatible conflicts, sbt provides dependency overrides. They are configured with the dependencyOverrides setting, which is a set of ModuleIDs. For example, the following dependency definitions conflict because spark uses log4j 1.2.16 and scalaxb uses log4j 1.2.17:

libraryDependencies ++= Seq(
  "org.spark-project" %% "spark-core" % "0.5.1",    
  "org.scalaxb" %% "scalaxb" % "1.0.0" ) 

The default conflict manager chooses the latest revision of log4j, 1.2.17:

show update 
[info] compile: 
[info]    log4j:log4j:1.2.17: ... ... 
[info]    (EVICTED) log4j:log4j:1.2.16 ... 

To change the version selected, add an override:

dependencyOverrides += "log4j" % "log4j" % "1.2.16"
