工程项目中同时包含scala和java代码，如果在java中调用scala的类，编译时可能会报找不到scala类的错误，出现这种问题的解决办法是需要对scala进行先行编译，具体需要在pom文件中添加一下plugin:
-
<plugin> -
<groupId>org.apache.maven.plugins</groupId> -
<artifactId>maven-compiler-plugin</artifactId> -
<configuration> -
<source>1.8</source> -
<target>1.8</target> -
<encoding>UTF-8</encoding> -
<maxmem>1024m</maxmem> -
<fork>true</fork> -
<compilerArgs> -
<arg>-Xlint:all,-serial,-path</arg> -
</compilerArgs> -
</configuration> -
</plugin> -
<plugin> -
<groupId>net.alchim31.maven</groupId> -
<artifactId>scala-maven-plugin</artifactId> -
<executions> -
<execution> -
<id>scala-compile-first</id> -
<phase>process-resources</phase> -
<goals> -
<goal>add-source</goal> -
<goal>compile</goal> -
</goals> -
</execution> -
</executions> -
</plugin>
