当使用kotlin maven插件时,我得到了一个不受支持的major.minor版本52.0.

我正在使用maven3.2.5,jdk1.7,kotlin1.1.2-2和intellij idea 2017.1.3. pom中的kotlin配置是由想法产生的,包括：

    <plugin>
        <groupId>org.jetbrains.kotlin</groupId>
        <artifactId>kotlin-maven-plugin</artifactId>
        <version>${kotlin.version}</version>
        <executions>
            <execution>
                <id>compile</id>
                <phase>compile</phase>
                <goals>
                    <goal>compile</goal>
                </goals>
            </execution>
            <execution>
                <id>test-compile</id>
                <phase>test-compile</phase>
                <goals>
                    <goal>test-compile</goal>
                </goals>
            </execution>
        </executions>
    </plugin>

和

<dependency>
    <groupId>org.jetbrains.kotlin</groupId>
    <artifactId>kotlin-stdlib-jre7</artifactId>
    <version>${kotlin.version}</version>
</dependency>
<dependency>
    <groupId>org.jetbrains.kotlin</groupId>
    <artifactId>kotlin-test</artifactId>
    <version>${kotlin.version}</version>
    <scope>test</scope>
</dependency>

我做错什么了吗？

ps,我刚检查了kotlin-maven-plugin-1.1.2-2.jar,并确保它是用jdk1.8编译的.那么,我该怎么做才能在jdk7中使用它？

最佳答案 所以我将项目sdk更改为jdk1.8,然后将maven编译器插件更改为1.7.

这似乎是唯一的方法.
