运行时异常-Datanucleus和GAE

Question

我是Google应用程序引擎和数据核的新手。 以下错误似乎是一些jar问题，但我不确定哪个数据核jar应该位于war / web-inf / classes文件夹中，哪些jar应该位于app engine SDK文件夹中。 我正在使用App Engine SDK 1.7.0。 我在数据核增强方面没有任何问题。

Caused by: java.lang.NoSuchMethodError: org.datanucleus.plugin.PluginManager.<init>(Lorg/datanucleus/PersistenceConfiguration;Lorg/datanucleus/ClassLoaderResolver;)V
    at org.datanucleus.OMFContext.<init>(OMFContext.java:159)

    at org.datanucleus.store.appengine.jdo.DatastoreJDOPersistenceManagerFactory.<init>(DatastoreJDOPersistenceManagerFactory.java:71)
<continued in next message>

在App Engine SDK文件夹中，还有其他各种文件夹，它们包含相同数据核文件的不同版本。

* 编辑：*将SDK更新到1.7.3之后，我注意到appengine-java-sdk-1.7.3 \\ lib \\ user \\ orm文件夹中存在以下JARS，这些是存在于此处的datanucleus jar。

datanucleus-core-1.1.5
datanucleus-jpa-1.1.5
datanucleus-appengine-1.0.10.final
jdo2-api-2.3-eb

我的war / web-inf / lib也包含上述所有jar和以下jar：

appengine-api-1.0-sdk-1.7.3.jar

我的例外已更改，现在是：

org.datanucleus.plugin.NonManagedPluginRegistry resolveConstraints: Bundle "org.datanucleus.api.jdo" requires "org.datanucleus" version "3.1.1" but the resolved bundle has version "3.1.1" which is outside the expected range.

Appengine JDO / JPA插件Wiki 很好地定义了该插件的每个版本所需的DataNucleus jar
