获取错误运行javac.exe编译器消息，同时在Eclipse中使用Ant [英] Getting Error running javac.exe compiler message, while using Ant in Eclipse

问题描述

当我在Eclipse中运行Ant构建时，我收到以下错误消息，Ant构建失败。

错误消息：运行javac.exe编译器时出错

构建停止的行

<$ p fork =truememoryinitialsize =512Mmemorymaximumsize =1G> $ p>
< classpath refid =classpath/>
< src path =$ {source.home}/>
< / javac>


以前有人遇到过类似的问题吗？或者有人知道这里有什么问题吗？

系统信息：Eclipse Helio，JDK 1.5

解决方案

我有同样的问题，问题是，在eclipse中java.home指的是JRE而不是JDK。我改变了它，构建是成功的。您可以执行以下操作将其更改为JDK：

首选项> Java>已安装JRE>添加...对于JRE类型，选择标准VM>下一步目录：选择您的JDK目录（而不是JRE）（在我的情况下：C：\Program Files\Java\jdk1.6.0_16），按OK。

现在，你回到'安装的JRE'，在这里也选择JDK。

下面的帖子有助于找到解决方案。
JAVA_HOME指向错误的地方

When I run my Ant build in Eclipse, I'm getting the following error message and the Ant build fails.

Error Message: Error running javac.exe compiler

Line where the build stops:

<javac destdir="${classes.home}" debug="on" fork="true" memoryinitialsize="512M" memorymaximumsize="1G">
        <classpath refid="classpath"/>
        <src path="${source.home}"/>
</javac>

Has anyone faced a similar problem before? or does anybody know what's wrong here?

System Information: Eclipse Helio, JDK 1.5

解决方案

I had the same problem and the issue was, in eclipse java.home was referring to JRE instead of JDK. I changed it and the build was successful. You can do the following to change it to JDK:

Preferences > Java > Installed JRE's > Add... For 'JRE Type' select 'Standard VM' > Next > Directory: select your JDK directory (instead of JRE) (in my case: C:\Program Files\Java\jdk1.6.0_16 ), press OK.

Now, you are back at 'Installed JRE's', select the JDK here also.

The below post helped in finding the solution. JAVA_HOME points to the wrong place
