用maven生成类路径文件

我最终使用了gmaven:

        <plugin>
            <groupId>org.codehaus.groovy.maven</groupId>
            <artifactId>gmaven-plugin</artifactId>
            <executions>
                <execution>
                    <phase>generate-resources</phase>
                    <goals>
                        <goal>execute</goal>
                    </goals>
                    <configuration>
                        <source>
                            def all = project.runtimeArtifacts.collect{
                                def aid = "${it.groupId}:${it.artifactId}:${it.version}"
                                def p = project.projectReferences[aid]
                                p?.build?.outputDirectory ?: it.file.path
                            } + project.build.outputDirectory
                            def file = new File(project.build.directory, ".classpath")
                            file.write(all.join(File.pathSeparator))
                        </source>
                    </configuration>
                </execution>
            </executions>
        </plugin>

代码有点复杂,因为我希望在可能的情况下找到指向目标/类的路径。如果不需要,可以这样做:

file.write(project.runtimeClasspathElements.join(File.pathSeparator))
