无法创建任务或类型Cobertura-Instrument

Question

嗨，我收到以下错误：

build.xml:61: Problem: failed to create task or type cobertura-instrument
Cause: The name is undefined.
Action: Check the spelling.
Action: Check that any custom tasks/types have been declared.
Action: Check that any <presetdef>/<macrodef> declarations have taken place.

构建.xml包含以下目标：

<target name="instrument" depends="init,compile">
        <!--
            Remove the coverage data file and any old instrumentation.
        -->
        <delete file="cobertura.ser"/>
        <delete dir="${instrumented.dir}" />
        <!--
            Instrument the application classes, writing the
            instrumented classes into ${build.instrumented.dir}.
        -->
        <cobertura-instrument todir="${instrumented.dir}">
            <!--
                The following line causes instrument to ignore any
                source line containing a reference to log4j, for the
                purposes of coverage reporting.
            -->
            <ignore regex="org.apache.log4j.*" />
            <fileset dir="${classes.dir}">
                <!--
                    Instrument all the application classes, but
                    don't instrument the test classes.
                -->
                <include name="**/*.class" />
                <exclude name="**/*Test.class" />
            </fileset>
        </cobertura-instrument>
    </target>

please let me know how to resolve the above error tanks in advance.

Answer 1

我发现官方文档中的指南有点误导。cobertura 文件夹中的 jar 文件在文件名中包含版本号，因此您无法复制和粘贴该元素。

试试这个：

<path id="cobertura.classpath">
    <fileset dir="${cobertura.dir}">
        <include name="cobertura*.jar" />
        <include name="lib/**/*.jar" />
    </fileset>
</path>

Answer 2

您是否使用 taskdef 来定义corbertura-instrument任务？

Ant

允许您创建可在 Ant 中使用的令人兴奋的新任务，但您需要告诉 Ant 这些任务是如何定义的以及如何执行它们。幸运的是，Corbertura准确地告诉你如何定义他们的taskdef。

我建议将所需的Corbertura罐子放在项目中的${basedir}/antlib/corbertura下。这样，当有人签出项目时，他们会自动获得所需的Corbertura jars，而不必将它们安装在他们的特定系统上：

<taskdef resource="tasks.properties">
    <path>
        <fileset dir="${basedir}/antlib/corbertura"/>
        <fileset dir="${lib.dir}/>"
    </path>
</taskdef>
