Question

我试图通过ant运行cobertura，使用jdk1.6.0.35，但在检测时获得异常。怎么解决？异常消息如下：

[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

Answer 1

你有没有将Cobertura添加到你的蚂蚁任务中？

请参阅： https://github.com/cobertura/cobertura/wiki/Ant-Task-Reference

我的样子如下：

    <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>

我已经通过将asm-3.3.1更改为asm-all-5.0.4解决了这个问题。

Answer 3

来自https://github.com/cobertura/cobertura/wiki/FAQ#classnotfoundexception-during-instrumentation：

＆＃34;这是因为在cobertura 2.0中的检测期间，我们使用ASM来重建.class文件。我们重建了stackmap，这是与java 7以及之后的任何东西兼容的要求。这并不意味着我们重新编译代码，但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。＆＃34;

你需要有asm，asm-analysis，asm-commons，asm-tree和asm-util jar。

此外，添加ant文件（build.xml）的辅助路径应该可以解决问题。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。
