如何使用分类器访问jar？ [英] How do I access a jar with a classifier?

问题描述

我有一个maven项目，可以将两个jar作为工件构建。版本号为0.7，一个工件以默认方式构建，第二个具有分类器。因此，在我的存储库中，它们看起来像这样：

  Tue Jun 10 08:06:12 MST 2014 14915 gokenizer-0.7 .pom 
 Tue Jun 10 08:06:12 MST 2014 40 gokenizer-0.7-core.jar.sha1 
 Tue Jun 10 08:06:12 MST 2014 40 gokenizer-0.7.pom.sha1 
 Tue Jun 10 08:06:12 MST 2014 32 gokenizer-0.7.jar.md5 
 Tue Jun 10 08:06:12 MST 2014 32 gokenizer-0.7.pom.md5 
 Tue Jun 10 08 ：06：12 MST 2014 37969843 gokenizer-0.7.jar 
 Tue Jun 10 08:06:12 MST 2014 41887392 gokenizer-0.7-core.jar 
 Tue Jun 10 08:06:12 MST 2014 32 gokenizer -0.7-core.jar.md5 
 Tue Jun 10 08:06:12 MST 2014 40 gokenizer-0.7.jar.sha1 
  

如您所见，带有分类器的jar将core作为其分类器。

存储库的路径是：

  http：//myhostname/plugin/repository/project/DomainIQCore/LastSuccessful/repository/com/example/domain/gokenizer/0.7 / 
  

一切都好吗？那么在构建我的项目时，如何实际指定我想要带有核心分类器的jar？

在我的build.scala文件中，我试过这个：

  libraryDependencies ++ = Seq（
com.example.domain％gokenizer％0.7％core 
），
  

然后我收到此错误：

  java.lang.IllegalArgumentException：无法将依赖项'com.example.domain #gokenizer; 0.7'添加到模块com.example＃domainiq_2的配置'core'。 10; 0.1.0-SNAPSHOT因为此配置不存在！ 
  

当我尝试这个时：

  libraryDependencies ++ = Seq（
com.example.domain％gokenizer％0.7-core
），
  

它显然错误地构建了存储库的路径：

  http：//myhostname/plugin/repository/project/DomainIQCore/LastSuccessful/repository/com/example/domain/gokenizer/0.7-core/gokenizer-0.7-core.pom 
  

我显然必须做错事。我认为第一种方式（以第4个字段为核心）是方式，但我不知道因为这种配置不存在意味着什么。既然它似乎甚至没有试图访问存储库，似乎我必须告诉SBT核心意味着什么？这对我来说没有意义，因为我认为它只是路径的一部分，而不是配置。

当我删除第4个字段时，它正确获取jar的非分类器版本，所以我知道存储库在那里工作...

帮助？

解决方案

当然，一如既往，发布问题并找到答案;）

说分类器好多次让我在Great Google Machine上尝试不同的搜索，这让我得到了答案。

 com.example.domain ％gokenizer％0.7分类器核心
  

不是百分号。 分类器作为关键字。我不知道。现在它编译。<​​/ p>

I have a maven project that builds two jars as artifacts. The version number is 0.7 and one artifact is built the "default" way and the second has a classifier. As such, in my repository, they look like this:

Tue Jun 10 08:06:12 MST 2014    14915   gokenizer-0.7.pom   
Tue Jun 10 08:06:12 MST 2014    40  gokenizer-0.7-core.jar.sha1 
Tue Jun 10 08:06:12 MST 2014    40  gokenizer-0.7.pom.sha1  
Tue Jun 10 08:06:12 MST 2014    32  gokenizer-0.7.jar.md5   
Tue Jun 10 08:06:12 MST 2014    32  gokenizer-0.7.pom.md5   
Tue Jun 10 08:06:12 MST 2014    37969843    gokenizer-0.7.jar   
Tue Jun 10 08:06:12 MST 2014    41887392    gokenizer-0.7-core.jar  
Tue Jun 10 08:06:12 MST 2014    32  gokenizer-0.7-core.jar.md5  
Tue Jun 10 08:06:12 MST 2014    40  gokenizer-0.7.jar.sha1

As you can see, the jar with the classifier has "core" as its classifier.

The path to the repository is:

http://myhostname/plugin/repository/project/DomainIQCore/LastSuccessful/repository/com/example/domain/gokenizer/0.7/

All good? So how do I actually specify that I want the jar with the "core" classifier when building my project?

In my build.scala file, I tried this:

  libraryDependencies ++= Seq(
    "com.example.domain" % "gokenizer" % "0.7" % "core"
  ),

But then I get this error:

java.lang.IllegalArgumentException: Cannot add dependency 'com.example.domain#gokenizer;0.7' to configuration 'core' of module com.example#domainiq_2.10;0.1.0-SNAPSHOT because this configuration doesn't exist!

And when I try this:

  libraryDependencies ++= Seq(
    "com.example.domain" % "gokenizer" % "0.7-core"
  ),

It clearly builds the path to the repository wrong:

http://myhostname/plugin/repository/project/DomainIQCore/LastSuccessful/repository/com/example/domain/gokenizer/0.7-core/gokenizer-0.7-core.pom

I must obviously be doing something wrong. I thought the first way (with the 4th field as "core") was the way, but I have no idea what "because this configuration doesn't exist" means. Since it doesn't appear to even be trying to hit the repository, it seems that I have to tell SBT what "core" means? That doesn't make sense to me because I thought it was just part of the path, not a "configuration" as such.

When I remove the 4th field, it properly gets the non-classifier version of the jar, so I know the repository is there and working...

Help?

解决方案

Of course, as always happens, post the question and find the answer ;)

Saying "classifier" so many times made me try a different search on the Great Google Machine which netted me the answer.

        "com.example.domain" % "gokenizer" % "0.7" classifier "core"

Not a percent sign. "classifier" as a keyword. I had no idea. Now it compiles.
