maven打包报错

maven打包报错

作者: Grey____ | 来源:发表于2018-08-24 15:37 被阅读0次

    问题描述:java、scala混用的情况下,maven打包,遇到找不到符号的报错。

    原因:若在java代码中调用了scala代码,则需先编译scala代码,后编译java代码。


    解决方案 :

    解决方案1:

    参考1:https://blog.csdn.net/ilvchocolate/article/details/75626921

    第一步:

    mvn clean scala:compile compile

    第二步:

    mvn package

    解决方案2:

    上文参考的pom.xml的build无效,故贴上我测试后可用的插件配置

    <build>
        <plugins>
            <plugin>
                <groupId>org.scala-tools</groupId>
