Question

我试图转换/使用我之前生成过的jacoco.exec。我正在使用google上的build.xml。在我的dir文件夹中，我在dir文件夹中有以下文件：

    build.xml   CompareNumbers.class  jacoco.exec  src
build.xml~  jacocoant.jar         Main.class   TestCompareNumbers.class

另外，src文件夹包含我的java类：

CompareNumbers.java  Main.java  TestCompareNumbers.java

我的build.xml：

    <?xml version="1.0" encoding="UTF-8"?>

            <!-- to produce reports in different formats. -->
            <html destdir="${result.report.dir}"/>

        </jacoco:report>
    </target>

    <target name="rebuild" depends="clean,compile,test,report"/>

</project>

不幸的是，每当我运行“ant report”或ant compile时，都会出现以下错误：

    /home/luci/workspace/dir/build.xml:26: The following error occurred while executing this line:
jar:file:/usr/share/ant/lib/jacocoant.jar!/org/jacoco/ant/antlib.xml:19: taskdef A class needed by class org.jacoco.ant.ReportTask cannot be found: org/jacoco/core/analysis/ICoverageVisitor
 using the classloader AntClassLoader[/home/luci/workspace/dir/jacocoant.jar]

转换jacoco.exec错误
