Question

我正在尝试从2.2更新播放到2.3，但我有几个错误抱怨DefaultReads不兼容。

[error] Could not access term time in package java,
[error] because it (or its dependencies) are missing. Check your build definition for
[error] missing or conflicting dependencies. (Re-run with `-Ylog-classpath` to see the problematic classpath.)
[error] A full rebuild may help if 'DefaultReads.class' was compiled against an incompatible version of java.
[error]       (jsObj \ "items").asOpt[JsArray] match {

Answer 1

问题是播放缓存依赖性。我不应该使用最新版本。在我使用与Play版匹配的版本之后，它可以正常工作。

＆＃34; com.typesafe.play＆＃34; ％＆＃34; play-cache_2.11＆＃34; ％＆＃34; 2.3.8＆＃34;

Answer 2

根据@ richard-close的建议，这个问题是由我的情况引起的，因为sbt使用了jdk7。

您可以使用

进行检查

sbt
> eval System.getProperty("java.version")
[info] ans: String = 1.7.0_80
> eval System.getProperty("java.home")
[info] ans: String = /usr/lib/jvm/java-7-oracle/jre

Play 2.3为DefaultReads出现了不兼容的错误
