怎么办OpenJPA的增强与ANT + IntelliJ IDEA的

问题描述

这是快把我逼疯了，我很震惊，是绝对useles。

下面是我：

• IntelliJ IDEA的11


• OpenJPA的2.1.1

由于OpenJPA的加入到使用的库列表中我已经有classpath中到OpenJPA它看起来像这样

 ＆LT;路径ID =library.openjpa.classpath＆GT;
    ＆LT;文件集DIR =$ {} BASEDIR / lib目录/ OpenJPA的＆GT;
        ＆LT; patternset REFID =library.patterns/＆GT;
    ＆LT; /文件集＆GT;
＆LT; /路径＆GT;
 

根据官方文档，我添加以下目标

 ＆lt;目标名称=提升＆GT;
    ＆LT;复制includeemptydirs =假todir =$ {} BASEDIR / lib目录/ OpenJPA的＆GT;
        ＆LT;文件集DIR =SRC排除=** / *的推出，** / * java的。/＆GT;
    ＆LT; /复制＆GT;    ＆LT;的taskdef NAME =openjpac类名=org.apache.openjpa.ant.PCEnhancerTask＆GT;
        ＆LT;类路径REFID =library.openjpa.classpath/＆GT;
    ＆LT; /＆的taskdef GT;    ＆LT; openjpac＆GT;
        ＆LT;类路径REFID =library.openjpa.classpath/＆GT;
    ＆LT; / openjpac＆GT;
＆LT; /目标与GT;
 

这让我异常

I tested with Process Monitor and can see that it opens and reads persistence.xml.

Some person filed bug having problems I have and the answer he got was that finding persistence.xml is not a source of problem.

Questions are:

1. What can I do to make it work ?
2. Can I make it work by skipping need for persistence.xml and just specifying pattern for .class files I want to be enhanced ?
3. It's more Ant question. How can I make OpenJPA enhancer to look for persistence.xml in directory other than where openjpa-2.1.1.jar resides ?

解决方案

So I couldn't make it work without undocumented propertiesFile. Here is version that works for me. Also specifying persistence-unit via # makes it fail with NullReferenceException.

<target name="enhance">
    <taskdef name="openjpac" classname="org.apache.openjpa.ant.PCEnhancerTask">
        <classpath refid="library.openjpa.classpath"/>
    </taskdef>

    <openjpac>
        <classpath refid="library.openjpa.classpath"/>
        <classpath location="${reporting.output.dir}"/>
        <config propertiesFile = "${basedir}/src/META-INF/persistence.xml"/>
    </openjpac>
</target>
