Maven enforcer没有检测到jdk 1.7

Question

我正在使用maven enforcer插件来强制执行jdk 1.7(我正在使用java.nio.file).出于某种原因,maven enforcer插件无法检测到jdk 1.7.

? ~/ java -version
java version "1.7.0_13"
Java(TM) SE Runtime Environment (build 1.7.0_13-b20)
Java HotSpot(TM) 64-Bit Server VM (build 23.7-b01, mixed mode)
? ~/ javac -version
javac 1.7.0_13
? ~/ mvn --version
Apache Maven 3.0.5 (r01de14724cdef164cd33c7c8c2fe155faf9602da; 2013-02-19 15:51:28+0200)
Maven home: /usr/local/Cellar/maven/3.0.5/libexec
Java version: 1.7.0_13, vendor: Oracle Corporation
Java home: /Library/Java/JavaVirtualMachines/jdk1.7.0_13.jdk/Contents/Home/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "mac os x", version: "10.7.5", arch: "x86_64", family: "mac"

这是我在pom.xml中的代码 -

   <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-enforcer-plugin</artifactId>
      <executions>
        <execution>
          <id>enforce-versions</id>
          <goals>
            <goal>enforce</goal>
          </goals>
          <configuration>
            <rules>
              <requireJavaVersion>
                <version>1.7</version>
              </requireJavaVersion>
            </rules>
          </configuration>
        </execution>
      </executions>
    </plugin>

这是我得到的错误 -

[INFO] --- maven-enforcer-plugin:1.2:enforce (enforce-versions) @ com.microsoft.gittf.core ---
[WARNING] Rule 0: org.apache.maven.plugins.enforcer.RequireJavaVersion failed with message:
Detected JDK Version: 1.6.0-43 is not in the allowed range 1.7.

编辑

mvn enforcer:display-info

显示版本1.7而不是1.6 ...为什么强制检测java版本1.6？

Answer 1

添加以下内容(如果缺少则创建此文件) ~/.mavenrc

export JAVA_HOME=/Library/Java/JavaVirtualMachines/{your-jdk-here}/Contents/Home

该.mavenrc仅由行家所以其他Java程序不会受到这一变化的影响回升.

Answer 2

版本解除是固定的.你给的是java的精确版本.永远记住,如果我们不确定我们应该使用的确切版本给出范围.将版本更改为[1.7,)

          <requireJavaVersion>
            <version>[1.7,)</version>
          </requireJavaVersion>

这意味着任何等于或大于1.7的版本都是可以接受的.
