如何指定 sbt 依赖关系以及预期的 JDK 版本

Question

如何在 Build.sbt 中指定依赖项的 JDK 版本？

我在 Aspose 库中遇到过这种情况，其中文件名后缀为 JDK 版本，即 aspose-email-4.8.0-jdk17.jar 而不是普通的 aspose-email-4.8.0.jar。因此，通常指定依赖关系，例如

"com.aspose" % "aspose-email" % "4.8.0"

会导致 sbt 抱怨以下错误，因为可怜的 SBT 试图下载一个不存在的文件：

[warn]  [FAILED     ] com.aspose#aspose-email;4.8.0!aspose-email.jar:  (0ms)
[warn] ==== local: tried
[warn]   /Users/developer/.ivy2/local/com.aspose/aspose-email/4.8.0/jars/aspose-email.jar
[warn] ==== public: tried
[warn]   https://repo1.maven.org/maven2/com/aspose/aspose-email/4.8.0/aspose-email-4.8.0.jar
[warn] ==== Aspose: tried
[warn]   http://maven.aspose.com/artifactory/simple/ext-release-local/com/aspose/aspose-email/4.8.0/aspose-email-4.8.0.jar

[warn]  ::::::::::::::::::::::::::::::::::::::::::::::
sbt.ResolveException: download failed: com.aspose#aspose-email;4.8.0!aspose-email.jar

更新然后我认为将 JDK 版本附加到版本号可能会修复它：

"com.aspose" % "aspose-email" % "4.8.0-jdk17"

不幸的是，它会导致 SBT 认为 POM 文件位于 aspose-email-4.8.0-jdk17.pom 而导致的另一个错误，而它应该是 aspose-email-4.8.0.pom.

我想如果你查看 repo，你会发现问题是由于不同的命名约定造成的——jar 文件后缀有预期的 JDK 版本，但 POM 文件不是。

Answer 1

谷歌搜索后，我发现 Maven 实际上有一个可选的额外坐标，即 分类器 ，它紧跟在版本号 (source) 之后.

要在 sbt 中使用它，您应该将依赖项定义为

"com.aspose" % "aspose-email" % "4.8.0" classifier "jdk17"
