CoberturaInstrumenter - 无法检测文件？

Question

我的项目正在使用Java 1.8和maven 3.2.1

我正在使用Corbetura插件

    <plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>cobertura-maven-plugin</artifactId>
        <version>2.6</version>
        <configuration>
            <format>xml</format>
            <maxmem>256m</maxmem>
            <aggregate>true</aggregate>
            <outputDirectory>shippable/codecoverage</outputDirectory>
        </configuration>
    </plugin>
    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
        <version>2.17</version>
        <dependencies>
            <dependency>
                <groupId>org.apache.maven.surefire</groupId>
                <artifactId>surefire-junit4</artifactId>
                <version>2.17</version>
            </dependency>
        </dependencies>
        <configuration>
            <redirectTestOutputToFile>true</redirectTestOutputToFile>
            <reportsDirectory>shippable/testresults</reportsDirectory>
        </configuration>
    </plugin>

然后我做

 mvn clean cobertura:cobertura  

我看到了以下

最后它说

Cobertura: Loaded information on 0 classes.

这里有什么不对？

Answer 1

更新05/10/2015:截至目前版本2.7(显然)支持这一点 - 谢谢@tomasz_kusmierczyk

看起来这是因为Cobertura 2.0.3依赖于ASM 4.1,它不支持Java 8.我设法通过强制cobertura-maven-plugin使用ASM 5.0.3来"修复"这个,但我不完全确定这是正确的做事方式.然而,它确实摆脱了所有这些警告.

        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>cobertura-maven-plugin</artifactId>
            <version>2.6</version>
            ...
            <dependencies>
                <dependency>
                    <groupId>org.ow2.asm</groupId>
                    <artifactId>asm</artifactId>
                    <version>5.0.3</version>
                </dependency>
            </dependencies>
        </plugin>

正确的方法可能是使用不同的代码覆盖工具,例如JaCoCo,它意味着支持Java 8.

更新:如果沿着这条路线走下去,看起来你会丢失一些代码覆盖率信息,所以另一个CC工具确实是要走的路.
