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，其中文件名以 JDK 版本为后缀，即aspose-email-4.8.0-jdk17.jar，而不是普通的aspose-email-4.8.0.jar。因此，通常指定依赖项，例如
"com.aspose" % "aspose-email" % "4.8.0"
将导致 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，由于 SBT 认为 POM 文件位于 aspose-email-4.8.0-jdk17.pom，而它应该是 aspose-email-4.8.0.pom，而导致另一个错误。

我认为，如果您查看 repo，您会发现问题是由于命名约定不同造成的 - 其中 jarfile 以预期的 JDK 版本为后缀，但 POM 文件不是。
