Rebased 现在面临 Scala 依赖问题
Rebased and now facing Scala dependency issues
我不太确定在 rebase 之前我的 rocket-chip 回购在哪里，但这是在转换为使用 Scala 2.12.4 之前（之前我在 2.11.12）。
在尝试重建之前，我已经重新定位并解决了几个 Chisel 文件和 运行 git submodule update rocket-chip 中的冲突。
我现在面临一个依赖问题，我认为它与 hardfloat 有关？

我已经尝试将 hardfloat 的头部移动到 Jack Koenig 的提交 7903547 中，它添加了一些 crossScalaVersions 设置以支持 2.12.14，但没有帮助。
这是升级到 2.12 的已知不幸副作用。据我所知，这是由于 SBT 中对多项目构建的支持有些参差不齐，但无论如何，都可以解决。
如果你看一下我将 rocket-chip 升级到 2.12 (https://github.com/freechipsproject/rocket-chip/pull/1431) 的 PR，你会发现我必须在命令行上的每个 SBT 调用中添加 ++2.12.4 .这是在告诉 SBT 强制所有项目（包括子项目）使用 Scala 版本。到目前为止，我一直无法弄清楚如何在 build.sbt 文件中执行此操作（如果阅读本文的任何人知道更好的解决方案，请告诉我们！）。
如果您使用 SBT 交互 shell，您需要输入 ++2.12.4 作为第一个命令，例如
jack@myhost:/home/jack/rocket-chip$ java -Xmx2G -Xss8M -XX:MaxPermSize=256M -jar sbt-launch.jar
