maven将一个本地类目录添加到模块的类路径中 [英] maven add a local classes directory to module's classpath

问题描述

我知道这有点超出了maven的范围，但我需要将一个带有编译类的本地目录添加到模块的类路径中。
我看到： Maven：添加一个文件夹或jar文件到当前的类路径，但这只适用于jar。

我需要一个类似的解决方案，但在目录中有编译的类本地文件系统。这甚至可能吗？

Thx！

解决方案

经过一番广泛的讨论研究，我发现我最好的选择是使用maven-antrun-plugin，在进程资源阶段，从类中生成一个jar，并将其作为系统范围和systemPath的依赖项添加到我刚刚构建的jar中。 p>

Pom片段：

 < plugin> 
< groupId> org.apache.maven.plugins< / groupId> 
< artifactId> maven-antrun-plugin< / artifactId> 
< version> 1.6< / version> 
< executions> 
< execution>

< target name =mpower.jar> 
< taskdef resource =net / sf / antcontrib / antcontrib.propertiesclasspath =$ {env.USERPROFILE} \.m2 \repository \-contrib -\\ant-contrib \1.0b3 \ant-的contrib-1.0b3.jar/> 
 
< if> 
< available file =$ {classes.dir}type =dir/> 
< then> 
< jar destfile =$ {env.TEMP} \classes.jar> 
< fileset dir =$ {classes.dir} \classes> 
< include name =** / **/> 
< / fileset> 
< / jar> 
< / then> 
< else> 
<失败消息=$ {classes.dir}未找到。跳过jar创建/> 
< / else> 
< / if> 
< / target> 
< / configuration> 
< / execution> 
< / executions> 
  

....

 < dependency> 
< groupId> ant-contrib< / groupId> 
< artifactId> ant-contrib< / artifactId> 
< version> 1.0b3< / version> 
< / dependency> 
< dependency> 
< groupId> com.my.code< / groupId>

< version> 1.1< / version> 
< scope> system< / scope> 
< systemPath> $ {env.TEMP} \classes.jar< / systemPath> 
< / dependency> 
  

I know this is a bit out of maven's scope, but I need to add a local directory with compiled classes to the module's classpath. I saw: Maven: add a folder or jar file into current classpath, but this is good for a jar only.

I need to have a similar solution but with compiled classes in a directory on local file system. Is this even possible?

Thx!

解决方案

After some extensive research, I found that my best option was to use the maven-antrun-plugin and during the process-resources phase, generate a jar from the classes and add it as dependency with system scope and systemPath to the jar I just built.

Pom snippets:

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.6</version>
<executions>
    <execution>

        <goals>
            <goal>run</goal>
        </goals>
        <configuration>
            <target name="mpower.jar">
                <taskdef resource="net/sf/antcontrib/antcontrib.properties" classpath="${env.USERPROFILE}\.m2\repository\ant-contrib\ant-contrib\1.0b3\ant-contrib-1.0b3.jar"/>

                <if>
                    <available file="${classes.dir}" type="dir"/>
                    <then>
                        <jar destfile="${env.TEMP}\classes.jar">
                            <fileset dir="${classes.dir}\classes">
                                <include name="**/**"/>
                            </fileset>
                        </jar>
                    </then>
                    <else>
                        <fail message="${classes.dir} not found. Skipping jar creation"/>
                    </else>
                </if>
            </target>
        </configuration>
    </execution>
</executions>
