通过Maven编译Java 7代码 [英] Compiling Java 7 code via Maven

问题描述

我的pom文件列表

<project>
  <build>
    <pluginManagement>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.0</version>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-surefire-plugin</artifactId>
                <version>2.12.4</version>
            </plugin>
        </plugins>
    </pluginManagement>
    <plugins>
        <plugin>
            <artifactId>maven-compiler-plugin</artifactId>
            <configuration>
                <source>1.7</source>
                <target>1.7</target>
            </configuration>
        </plugin>
    </plugins>
  ...

但是 mvn clean install ，我得到了

[INFO] -------------------------------------------------------------
[ERROR] COMPILATION ERROR : 
[INFO] -------------------------------------------------------------
[ERROR] Failure executing javac, but could not parse the error:
javac: invalid target release: 1.7
Usage: javac <options> <source files>

/ usr / bin / java -version 是（哪个java 指向此处）

java version "1.7.0_10"
Java(TM) SE Runtime Environment (build 1.7.0_10-b18)
Java HotSpot(TM) 64-Bit Server VM (build 23.6-b04, mixed mode)

javac 也指向正确的Java版本

javac also points to the correct Java version

/usr/bin/javac -> /Library/Java/JavaVirtualMachines/jdk1.7.0_10.jdk/Contents/Home/bin/javac

在这台机器上，我使用 zsh （ echo $ 0 返回 -zsh ）

On this machine, I am using zsh (echo $0 returns -zsh)

在我的 .zshrc 中，我定义了：

 33 # HOME
 34 JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_10.jdk/Contents/Home
 35 SCALA_HOME=/Library/Scala/current
 36 FORGE_HOME=~/tools/forge/
 37 
 38 # PATH
 39 PATH="/Library/Frameworks/Python.framework/Versions/3.2/bin:${PATH}"
 40 PATH=${PATH}:${JAVA_HOME}/bin
 41 PATH=${PATH}:/bin/
 42 PATH=${PATH}:/sbin/
 43 PATH=${PATH}:/usr/bin/
 44 PATH=${PATH}:/usr/sbin/
 45 PATH=${PATH}:/opt/local/bin/
 46 PATH=${PATH}:/opt/local/sbin/
 47 PATH=${PATH}:/usr/local/git/bin
 48 PATH=${PATH}:/usr/local/git/sbin
 49 PATH=${PATH}:/Applications/Xcode.app/Contents/Developer/usr/bin
 50 PATH=${PATH}:${SCALA_HOME}/bin
 51 PATH=${PATH}:${FORGE_HOME}/bin
 52 
 53 export PATH

当我运行 mvn clean install --debug 我看到其实我使用Java 6

When I am running mvn clean install --debug I see that in fact I use Java 6

  1 Apache Maven 3.0.3 (r1075438; 2011-02-28 11:31:09-0600)
  2 Maven home: /usr/share/maven
  3 Java version: 1.6.0_35, vendor: Apple Inc.
  4 Java home: /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home

可以定义吗？我有多次来源（d）我的.zshrc。

Where could it be defined? I have source(d) my .zshrc multiple times.

推荐答案

检查 mvn 脚本，看看它是如何构建命令的。也许你或其他人在那里硬编码 JAVA_HOME 而忘记了它。

Check the mvn script in your maven installation to see how it's building the command. Perhaps you or someone else has hard-coded a JAVA_HOME in there and forgotten about it.
