我运行代码覆盖率目标：

<junit fork="yes" dir="${basedir}" failureProperty="test.failed">
        <!--
                        Note the classpath order: instrumented classes are before the
                        original (uninstrumented) classes.  This is important.
                -->
        <classpath path="${instrumented.dir}" />
        <classpath path="${classes.dir}" />
        <classpath refid="classpath" />
        <!--
                        The instrumented classes reference classes used by the
                        Cobertura runtime, so Cobertura and its dependencies
                        must be on your classpath.
                -->
        <classpath refid="cobertura.classpath" />

        <formatter type="xml" />
        <!--<test name="${testcase}" todir="${reports.xml.dir}" if="testcase" />-->
        <batchtest fork="yes" todir="${reports.xml.dir}">
                <fileset dir="${classes.dir}">
                        <include name="**/generated/AllTests.class" />
                </fileset>
        </batchtest>
</junit>

<junitreport todir="${reports.xml.dir}">
        <fileset dir="${reports.xml.dir}">
                <include name="TEST-*.xml" />
        </fileset>
        <report format="frames" todir="${reports.html.dir}" />
</junitreport>

然后我得到以下输出（使用 fork="true" 时）：

This is known to happen on Linux kernel 2.6.20.
Make sure cobertura.jar is in the root classpath of the jvm 
process running the instrumented code.  If the instrumented code 
is running in a web server, this means cobertura.jar should be in 
the web server's lib directory.
Don't put multiple copies of cobertura.jar in different WEB-INF/lib directories.
Only one classloader should load cobertura.  It should be the root classloader.

我正在使用 Ant 1.7.0 和 cobertura 1.9.2。

任何想法为什么没有覆盖？正如我在目标中看到的那样，测试运行正常。我曾尝试切换 java 版本（1.5.0_06 和 1.6.0_10），但没有区别。

我发现设置环境属性成功cobertura.use.java.nio=false。

由于我使用的是 ant，因此我只是cobertura-build.xml通过在命令中添加以下内容来编辑文件<junit>：

<junit fork="yes">
  <jvmarg value="-Dcobertura.use.java.nio=false"/>
  ...
</junit>

你的 cobertura 在构建过程中崩溃了。

您可以尝试将Cobertura升级到版本 1.9.3 或 1.9.4.1。不过，我在使用 1.9.4.1 时遇到了一些问题，我目前使用的是 1.9.3。
