使用 Maven 和 Netbeans 为 1.6 编译 java 源 1.7 [英] compile java source 1.7 for 1.6 with Maven and Netbeans

问题描述

我有一个为 java 1.7 编写的源代码.我想为 java 1.6 编译它.如果我理解正确，我需要使用选项 -source 1.7 -target 1.6

I have a source code written for java 1.7. I would like to compile it for java 1.6. If I understood correctly, I need to use the options -source 1.7 -target 1.6

我正在使用 Maven2 和 Netbeans (8.0).所以，我试过了:

I am using Maven2 and Netbeans (8.0). So, I tried :

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.2</version>
            <configuration>
                <source>1.7</source>
                <target>1.6</target>
                <compilerArguments>
                    <bootclasspath>/usr/lib/jvm/java-6-openjdk-amd64/jre/lib/rt.jar</bootclasspath>
                </compilerArguments>
            </configuration>
        </plugin>

但我得到一个 javacTask: source release 1.7 requires target release 1.7

我读到有些人使用 eclipse 编译器来使其工作，但是如果我使用的是 Netbeans，我该怎么做?

I read that some people use eclipse compiler to make it work, but how can I do this if I'm using Netbeans ?

非常感谢您的帮助

推荐答案

EDIT 抱歉，情况正好相反.您可以编译源 1.6 和目标 1.7，但是当源版本 > 目标版本时不能编译它，因为这样它无法处理语言的新功能.

EDIT Sorry it's the other way around. You can compile source 1.6 and target 1.7 but you can't compile it when source version > target version because then it couldn't handle new features of the language.

有关这方面的更多详细信息，请参阅 javac 文档中的交叉编译选项 http://docs.oracle.com/javase/7/docs/technotes/tools/windows/javac.html.

For more detail about this see Cross-Compilation Options in javac documentation http://docs.oracle.com/javase/7/docs/technotes/tools/windows/javac.html.

如果你有 1.6 源代码，你可以像这样为目标版本 1.7 编译它们:

If you would have 1.6 sources you could compile them for target version 1.7 like this:

<project>
  [...]
  <build>
    [...]
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>3.2</version>
        <configuration>
          <source>1.6</source>
          <target>1.7</target>
        </configuration>
      </plugin>
    </plugins>
    [...]
  </build>
  [...]
</project>>
