Class broken error with Joda Time using Scala
提问by Hyman
I'm adding the Joda Time repository to SBT with
我正在将 Joda Time 存储库添加到 SBT
libraryDependencies ++= Seq(
"joda-time" % "joda-time" % "2.1"
)
Then I merrily use it like this:
然后我愉快地使用它：
val ymd = org.joda.time.format.DateTimeFormat.forPattern("yyyyMMdd")
ymd.parseDateTime("20121212")
But, when I compile the project in SBT, I get a nasty:
但是，当我在 SBT 中编译项目时，我得到了一个讨厌的信息：
[warn] Class org.joda.convert.FromString not found - continuing with a stub.
[warn] Caught: java.lang.NullPointerException while parsing annotations in /home/Hyman/.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/Hyman/.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)
I tried the 2.0 version of joda-time, but get the same error.
我尝试了 joda-time 的 2.0 版本，但得到同样的错误。

Add this dependency:
添加此依赖项：
"org.joda" % "joda-convert" % "1.8.1"
“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.
它是 joda-time 的可选依赖项。我必须将它添加到我自己的项目中，以便 Scala 编译器接受使用 joda-time jar。
Your issue seems to be the same.
你的问题似乎是一样的。

I was running into a similar issue:
我遇到了类似的问题：
[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.jarresolved the issue.
显式添加依赖项jcip-annotations-1.0.jar解决了该问题。
