目标版本无效:1.7

Question

我见过类似的问题,但还没有找到答案.

使用maven编译,我得到:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.0:compile (default-compile) on project api: Fatal error compiling: invalid target release: 1.7 -> [Help 1]

这是pom.xml:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.0</version>
    <configuration>
        <source>1.7</source>
        <target>1.7</target>
        <encoding>UTF-8</encoding>
    </configuration>
</plugin>

Javac版本:

javac 1.7.0_25

Java版本:

java version "1.7.0_25"
Java(TM) SE Runtime Environment (build 1.7.0_25-b15)
Java HotSpot(TM) 64-Bit Server VM (build 23.25-b01, mixed mode)

知道它可能是什么？

Answer 1

您需要将JAVA_HOME设置为jdk7主目录,例如在Microsoft Windows上:

• "C:\ Program Files\Java\jdk1.7.0_40"

或在OS X上:

• /Library/Java/JavaVirtualMachines/jdk1.7.0_40.jdk/Contents/Home

Answer 2

除了设置JAVA_HOME环境变量之外,您还必须确保在Maven运行配置中使用正确的JDK.转到Run - > Run Configuration,选择Maven Build配置,转到JRE选项卡并设置正确的Runtime JRE.
