Ant 带有JDK 1.6.0_35的Cobertura 2.0.3未能对类进行仪表化

我试图通过ant运行cobertura，使用jdk1.6.0.35，但在检测时遇到异常。如何解决？ 异常消息如下所示：

[cobertura-instrument] [12/06 13:19:26] [WARN] CoberturaInstrumenter: Unable to instrument file D:\workcontext\niyong_crm_v1_0\crm\code\ulcif\web\WEB-INF\classes\com\ulic\ulcif\ws\service\impl\CustomerCIImpl.class

您是否已将Cobertura添加到ant任务中

见：

我的看起来像这样：

    <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}/classes" >
                 <include name="**/*.class" />
                 <exclude name="**/*Test.class" />
            </fileset>
            <auxClasspath>
              <path refid="cobertura.auxpath" />
            </auxClasspath>
        </cobertura-instrument> 
    </target>

我通过将asm-3.3.1更改为asm-all-5.0.4解决了这个问题。

来自：

“这是因为在cobertura 2.0的插装过程中，我们使用ASM来重建.class文件。我们重新构建了stackmap，这是与Java7及以后任何版本兼容的要求。这并不意味着我们要重新编译代码，但是ASM要求我们提供其他类的二进制文件，以防它需要查找任何超级方法。为了解决这个问题，我们使用了一个名为auxClasspath的参数。”

您需要有asm、asm分析、asm公用程序、asm树和asm util JAR

另外，在ant文件（build.xml）中添加auxpath应该可以解决这个问题。 尝试添加以下代码：

<path id="cobertura.auxpath">
<pathelement location="${bin}"/>
    </path>

    <target name="instrument_coverage" depends="init_coverage"
        description="Instruments source code for coverage measurement">
        <cobertura-instrument datafile="${coverage.datafile}">
            <fileset refid="coverage-files"/>
        <auxClasspath>
              <path refid="cobertura.auxpath" />
            </auxClasspath>
        </cobertura-instrument>
    </target>

这对我有用
