Currently I'm running into this when simply trying to call a .count()on my MongoDB collection.

目前，当我只是尝试.count()在我的 MongoDB 集合上调用 a 时遇到了这个问题。

Upon Googling, it seems like it may be caused by dependency issues. The thing is, I'm using Scalatra just to serve an API and actually don't require any of the scalate stuff. I commented out all references to it, but I still get this. Could it be a dependency issue between the libraries I'm using?

在谷歌上搜索，它似乎可能是由依赖问题引起的。问题是，我使用 Scalatra 只是为了提供 API，实际上不需要任何 scalate 东西。我注释掉了所有对它的引用，但我仍然得到了这个。这可能是我使用的库之间的依赖问题吗？

In my company we had this problem with CharSequence. This is due to Scala 2.10.x does not work with Java 8. This was described in Scalas mailinglist. Switch back to Java 7.

在我的公司，我们遇到了 CharSequence 的这个问题。这是由于斯卡拉2.10.x不与Java 8这项工作在Scalas被描述邮件列表。切换回 Java 7。

I have a similar problem on Java 1.8.0 working with Scala 2.10.4 and sbt 0.12.4. But when upgrading to sbt 0.13.7, the problem is solved.

我在使用 Scala 2.10.4 和 sbt 0.12.4 的 Java 1.8.0 上有类似的问题。但是升级到sbt 0.13.7后，问题就解决了。

I am seeing the same issue with software requiring Scala 2.9.2+ and Java 1.7 running on Scala 2.10.4 and Java 1.8. Changed to Java 7 via sudo update-alternatives --config java

I also got the same issue in Ubuntu 14.04 but I solved by removing the scala 2.10 and installing 2.11

我在 Ubuntu 14.04 中也遇到了同样的问题，但我通过删除 scala 2.10 并安装 2.11 解决了

wget www.scala-lang.org/files/archive/scala-2.11.7.deb

 

 

dpkg -i scala-2.11.7.deb

Now try.

现在试试。

That was a lot of reconfiguration for me to get it to work, here is my (NOW) working build.sbt using, sbt 0.13.15 and scala 2.10.4 and jdk 1.8.1_131

这对我来说是很多重新配置才能让它工作，这是我（现在）正在使用的 build.sbt，sbt 0.13.15 和 scala 2.10.4 和 jdk 1.8.1_131
