Question

我有三个模块：客户端，共享，服务器。

服务器是＆＃34;正常＆＃34; Kotlin模块，编译为JVM ByteCode。应该将Share编译为JS和JVM ByteCod 客户端仅编译为JS。

我有设置共享来编译JS和ByteCode - 这很好用。问题是，客户端模块无法编译，因为它没有从客户端看到类。

Kotlin代码：

import com.a.typical.super.long.package.which.contains.ModelId

interface ClientOrca {

  fun test(): ModelId
}

[ERROR] <ClientKt>:[1,8] Unresolved reference: com
[ERROR] <ClientKt>:[5,15] Unresolved reference: ModelId

如何设置一个项目（使用maven），以便我的代码（分成几个maven模块）一次编译成一个JS文件？

解决方案确实在kotlin的github examples。以下是摘要：

库必须生成一个包含js文件和* .class文件的jar文件。要实现这一点，你必须告诉kotlin编译器生成js文件并将它们放入类文件夹中，并将所有kotlin文件编译为类目录中的* .class文件（目标/类）

                        <sourceDir>${project.basedir}/src/main/java</sourceDir>
                    </sourceDirs>
                    <outputFile>${project.build.outputDirectory}/${project.artifactId}.js</outputFile>  <!-- super important! -->

                </goals>
                <configuration>
                    <sourceDirs>
                        <sourceDir>${project.basedir}/src/test/kotlin</sourceDir>
                        <sourceDir>${project.basedir}/src/test/java</sourceDir>

在使用该库的js项目中，您必须告诉maven解压缩依赖项并使js文件可用。通过以下方式更改pom.xml：

    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-dependency-plugin</artifactId>
        <executions>
            <execution>
                <id>unpack</id>
                <phase>compile</phase>
                <goals>
                    <goal>unpack</goal>
                </goals>
                <configuration>
                    <artifactItems>
                        <artifactItem>
                            <groupId>org.jetbrains.kotlin</groupId>
                            <artifactId>kotlin-stdlib-js</artifactId>
                            <version>${kotlin.version}</version>
                            <outputDirectory>${project.build.directory}/js/lib</outputDirectory>
                            <includes>*.js</includes>
                        </artifactItem>
                        <artifactItem>
                            <groupId>ch.viseon.openOrca</groupId>
                            <artifactId>share</artifactId>
                            <version>${project.version}</version>
                            <outputDirectory>${project.build.directory}/js/lib</outputDirectory>
                            <includes>*.js</includes>
                        </artifactItem>
                    </artifactItems>
                </configuration>
            </execution>
        </executions>
    </plugin>
