使用 Cobertura 2.0.3、Java 7 和 Ant 的 ExceptionInInitializerError

Question

我正在尝试在将使用 Cobertura 2.0.3 的 Ant 项目上升级到 Java 7。

build.xml 中的 Cobertura 目标：

<target name="process-classes" depends="compile" description="post-process the generated files from compilation, for example to do bytecode enhancement on Java classes.">
        <path id="cobertura.auxpath">
              <pathelement path="${target.dir}/classes"/>
              <pathelement location="classes"/>
        </path>

        <mkdir dir="${target.dir}/cobertura-ser" />
        <mkdir dir="${target.dir}/cobertura-classes" />

        <!-- Copy all the files into the file that eventually get's built into the instrumented JAR -->
        <copy todir="${target.dir}/cobertura-classes">
            <fileset dir="${target.dir}/classes" /> 
        </copy>

        <!-- Instrument all the classes in place -->
        <cobertura-instrument todir="${target.dir}/cobertura-classes" 
            datafile="${target.dir}/cobertura-ser/cobertura.ser" 
            classpathref="cobertura.path">
            <fileset dir="${target.dir}/cobertura-classes" >
                <include name="**/*.class" />
            </fileset>
            <auxClasspath>
              <path refid="cobertura.auxpath" />
            </auxClasspath>
        </cobertura-instrument> 
    </target>

我在构建的检测阶段看到 ClassNotFoundException 和 ExceptionInInitializerError。

我做错了什么？

Answer 1

如果我对此块发表评论，错误将得到解决：

<fileset dir="${target.dir}/cobertura-classes" >
    <include name="**/*.class" />
</fileset>

我不知道为什么。如果您知道，请发布答案。

我明白了：

process-classes:
    [mkdir] Created dir: C:\code\policy\main\policy-base\target\cobertura-ser
    [mkdir] Created dir: C:\code\policy\main\policy-base\target\cobertura-classes
     [copy] Copying 465 files to C:\code\policy\main\policy-base\target\cobertura-classes

[cobertura-instrument] INFO: Cobertura: Saved information on 0 classes.  

这是否意味着没有类被检测？

[编辑] 我改变了这个，并且课程正在被检测。但是我的构建因超时问题而失败。

<fileset dir="${target.dir}/classes" >
    <include name="**/*.class" />
    <exclude name="**/*Test.class" />
</fileset>
