CoberturaInstrumenter - Unable to instrument file?

提问by daydreamer

My project is using Java 1.8and maven 3.2.1

我的项目正在使用Java 1.8和maven 3.2.1

I am using Corbeturaplugin as

我使用Corbetura插件作为

    <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>

        <dependencies>
            <dependency>

            <reportsDirectory>shippable/testresults</reportsDirectory>
        </configuration>
    </plugin>

and then I do

然后我做

 mvn clean cobertura:cobertura  

and I see following

我看到以下

at the end it says

最后它说

Cobertura: Loaded information on 0 classes.

Whats wrong here?

这里有什么问题吗？

Update 05/10/2015: As of now version 2.7 (apparently) supports this - thanks @tomasz_kusmierczyk

2015 年 5 月 10 日更新：截至目前 2.7 版（显然）支持这一点 - 感谢 @tomasz_kusmierczyk

Looks like this is because Cobertura 2.0.3 depends on ASM 4.1, which doesn't support Java 8. I managed to "fix" this by forcing cobertura-maven-plugin to use ASM 5.0.3, but I'm not completely sure that this is the correct way of doing things. It did however get rid of all of those warnings.

看起来这是因为 Cobertura 2.0.3 依赖于不支持 Java 8 的 ASM 4.1。我设法通过强制 cobertura-maven-plugin 使用 ASM 5.0.3 来“修复”这个问题，但我不完全确定这是正确的做事方式。然而，它确实消除了所有这些警告。

        <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>

The right way to go is probably to use a different code coverage tool, like JaCoCowhich is meant to have support for Java 8.

正确的做法可能是使用不同的代码覆盖工具，例如JaCoCo，它旨在支持 Java 8。

Update: Looks like you lose some code coverage info if you go down this route, and so another CC tool is indeed the way to go.

更新：如果你沿着这条路走，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。

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

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

"This is because during instrumentation in cobertura 2.0, we use ASM to rebuild the .class files. We rebuild the stackmap which is a requirement to be compatible with java 7 and anything after. This does not mean that we recompile the code, however ASM requires that we provide the binaries of the other classes just in case it needs to look up any super methods. To fix this we use an argument called auxClasspath."

“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。我们重建堆栈映射，这是与 java 7 和之后的任何内容兼容的要求。这并不意味着我们重新编译代码，但是 ASM要求我们提供其他类的二进制文件，以防万一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。”

Adding the following code to your ant file (build.xml) should resolve the issue.

将以下代码添加到您的 ant 文件 (build.xml) 应该可以解决该问题。

<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>

This worked for me.

这对我有用。
