使用 Scala 的 Joda Time 类中断错误

将 Joda Time 存储库添加到 SBT

libraryDependencies ++= Seq(
"joda-time"         % "joda-time"           % "2.1"
)

然后我就像这样快乐地使用它:

 val ymd = org.joda.time.format.DateTimeFormat.forPattern("yyyyMMdd")
ymd.parseDateTime("20121212")

但是，当我在 SBT 中编译这个项目时，我得到了一个令人讨厌的结果:

[warn] Class org.joda.convert.FromString not found - continuing with a stub.
[warn] Caught: java.lang.NullPointerException while parsing annotations in /home/jack/.ivy2/cache/joda-time/joda-time/jars/joda-time-2.1.jar(org/joda/time/DateTime.class)
[error] error while loading DateTime, class file '/home/jack/.ivy2/cache/joda-time/joda-time/jars/joda-time-2.1.jar(org/joda/time/DateTime.class)' is broken
[error] (class java.lang.RuntimeException/bad constant pool tag 10 at byte 42)

我尝试了 joda-time 的2.0版本，但是得到了相同的错误。

最佳答案

Add this dependency:

"org.joda" % "joda-convert" % "1.8.1"

It's an optional dependency of joda-time. I had to add it in my own project for the scala compiler to accept working with the joda-time jar.

Your issue seems to be the same.

I was running into a similar issue: 

[warn] Class net.jcip.annotations.NotThreadSafe not found - continuing with a stub.
[warn] Caught: java.lang.NullPointerException while parsing annotations in ~/.ivy2-p2/cache/org.opensaml/xmltooling/jars/xmltooling-1.3.4.jar(org/opensaml/xml/util/IDIndex.class)
[error] error while loading AttributeMap, class file '~/.ivy2-p2/cache/org.opensaml/xmltooling/jars/xmltooling-1.3.4.jar(org/opensaml/xml/util/AttributeMap.class)' is broken
[error] (class java.lang.RuntimeException/bad constant pool index: 0 at pos: 12058)

Explicitly adding a dependency jcip-annotations-1.0.jar resolved the issue.
