如何在NetBeans IDE中将Scala和Java文件一起编译？

Question

I have checked all the related questions about this issue. The issue i have is, i have scala code and java code in same netbeans project. The home env for scala is set. I use windows system for the development. I know that the build.xml of the netbeans project needs to be changed, to compile scala code first and then compile the java code. But i couldnt find much of example to do this on netbeans IDE.

Answer 1

I use the netbeans sbt plugin (nbsbt). It takes care of this transparently.

Answer 2

Only tangentially related, but Intellij Idea using pom (maven) projects handles this with no issues whatsoever. You just create a src/main/scala dir alongside your srce/main/java and use the Scala complier plug-in:

        <plugin>
            <groupId>org.scala-tools</groupId>
            <artifactId>maven-scala-plugin</artifactId>
            <executions>
                <execution>
                    <id>compile</id>
                    <goals>
                        <goal>compile</goal>
                    </goals>
                    <phase>compile</phase>
                </execution>
                <execution>
                    <id>test-compile</id>
                    <goals>
                        <goal>testCompile</goal>
                    </goals>
                    <phase>test-compile</phase>
                </execution>
                <execution>
                    <phase>process-resources</phase>
                    <goals>
                        <goal>compile</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

I offer this only for those who may be pondering NetBeans vs. Idea for Scala development.
