缺少依赖项'；类javax.jdo.spi.PersistenceCapable$ObjectedFieldSupplier'；，model.jar所需（model/error/error.class）

在针对JDO增强的Java模型编译有效代码时，我会遇到编译错误。我对这些错误感到困惑，因为没有直接使用Scala中讨论的包私有静态成员接口。我知道Scala不支持从Scala代码中使用这样的接口，但我对Scala编译器抱怨这些接口感到困惑

以下是我得到的错误：

[scalac] Compiling 3 scala and 196 java source files to /home/alain/Documents/Project/build/model/src
[scalac] error: error while loading Error, Missing dependency 'class javax.jdo.spi.PersistenceCapable$ObjectIdFieldSupplier', required by /home/alain/Documents/Project/model/dist/model.jar(model/error/Error.class)

以下是我用来编译的Ant代码段：

<target name="compile" depends="jar">
    <depend srcdir="src" destdir="${src.classes.dir}" cache="${build.dir}/src_dependencies" />
    <scalac srcdir="src" destdir="${src.classes.dir}" classpathref="src.build.classpath">
        <include name="**/*.scala"/>
        <include name="**/*.java"/>
    </scalac>
    <javac srcdir="src" destdir="${src.classes.dir}" source="1.6" target="1.6" nowarn="on"
       debug="on" encoding="UTF-8" classpathref="src.build.classpath" />
</target>

带有增强类的model.jar位于src.build.classpath上

我不明白为什么scalac关心Java类的依赖关系，如果它们不影响编译Scala源代码的知识，它就无法解决这些依赖关系

---

有趣的是，IntelliJ的Scala插件能够编译并运行此代码。

将增强的代码保留在scalac构建类路径之外。不过，为了编译，您仍然需要未增强的代码

下面是我如何解决这个问题的：

将常规JAR名称改为model-api.JAR（继承的目标使用src.classes.dir）

我在

src.build.classpath

中使用model-api.jar而不是model.jar构建依赖项

以下是增强目标的摘要：

<property name="production.enhanced.dir" value="${production.classes.dir}/../enhanced" />
<copy todir="${production.enhanced.dir}">
    <fileset dir="${production.classes.dir}" />
</copy>
<jdodoclet ...>
<jdoc ...>
<jar destfile="dist/model.jar"> <fileset dir="${production.enhanced.dir}" />
    <fileset dir="src" excludes="**/*.java */.jj */.scala */.groovy" />
</jar>

我必须制作的值得注意的版本是将未增强的类复制到沙盒目录，在沙盒目录上运行JDO增强，并生成一个具有原始名称的运行时JAR
