Maven编译错误:重复的类 [英] maven compilation error: duplicate classes

问题描述

在我的maven2项目中，我有一个目录${basedir}/autogen，其中包含一些由wsdl2java生成的自动生成的源代码文件.

In my maven2 project I have a directory ${basedir}/autogen that contains some autogenerated source code files produced by wsdl2java.

运行mvn compile时，由于类重复，我得到了一个编译错误，该错误驻留在${basedir}/autogen中.这是真实的.但是${basedir}/autogen中的编译阶段在做什么?我没有告诉过maven将此目录添加为源目录. 而且似乎没有办法告诉Maven忽略目录.

When running mvn compile I get an compilation error, because of duplicate classes, that lives in ${basedir}/autogen. This is true. But what is the compilation phase doing in ${basedir}/autogen? I have not told maven to add this directory as a source directory. And there seems to be no way of telling maven to ignore the directory.

推荐答案

在使用maven-processor-plugin时，我遇到了同样的问题，发现解决方案是按以下方式配置maven-compiler插件:

I had the same problem when using the maven-processor-plugin and found that the solution was to configure the maven-compiler plugin as follows:

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>2.1</version>
            <configuration>
                <source>1.6</source>
                <target>1.6</target>
                <compilerArgument>-proc:none</compilerArgument>
            </configuration>
        </plugin>

-proc:none意味着无需注释处理即可进行编译，因此没有重复的类(通常在generate-sources阶段生成)

-proc:none means that compilation takes place without annotation processing and therefore no duplicate classes (which are typically generated in the generate-sources phase)

我希望能帮上忙.
