Eclipse编译将大量.class文件放入包文件夹中

发布于 2024-12-24 15:47:52 字数 618 浏览 2 评论 0原文

我一定是做了一些非常愚蠢的事情才导致了下面的情况。基本上，在编译了我之前多次成功编译的代码之后，所有 .class 文件突然都被放入了 .java 文件所在的包文件夹中。一些 .class 文件的名称中包含偶数，例如。

ClassName.java
ClassName.class
ClassName$1.class
ClassName$2.class
ClassName$3.class
ClassName$4.class

它在导航器中看起来一团糟，重建或清理项目并不会让这些文件消失。

我所做的最后一次代码更改（现已恢复）是在类静态字段中：

static {
    if (System.getProperty("os.name").startsWith("Mac OS X")) { CONTROL_PANEL_WIDTH = 225; }
    else { CONTROL_PANEL_WIDTH = 180; }

System.out.println(System.getProperty("os.name")); // this is what I added; perhaps it was stupid
}

我一定做了一些愚蠢的事情。你能帮忙吗？

原文

I must have done something very stupid which has caused the following situation. Basically after compilation of code which I had compiled successfully lots of times previously, all of the .class files have all of a sudden been put in the package folders, where the .java files are. Some of the .class files have even numbers in the names like.

ClassName.java
ClassName.class
ClassName$1.class
ClassName$2.class
ClassName$3.class
ClassName$4.class

It looks a mess in the Navigator and rebuilding or cleaning the project doesn't make these files go away.

The last code change I made, which has now been reverted was in the class static field:

static {
    if (System.getProperty("os.name").startsWith("Mac OS X")) { CONTROL_PANEL_WIDTH = 225; }
    else { CONTROL_PANEL_WIDTH = 180; }

System.out.println(System.getProperty("os.name")); // this is what I added; perhaps it was stupid
}

I must have done something silly. Can you help please?

您可能已经切换了类的默认输出文件夹，可以通过右键单击您的项目 -> 来修复该文件夹。 属性 -> Java 构建路径 ->选项卡源 -> 默认输出文件夹（将其设置为/bin）

您还可以检查工作区中的.classpath 文件，该文件必须查看像这样（输出文件夹的路径是相对存储的）：

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
    <classpathentry kind="src" path="src"/>
    <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.6"/>
    <classpathentry kind="output" path="bin"/>
</classpath>

You might have switched your default output folder of your classes, which can be fixed by right click your project -> Properties -> Java Build Path -> Tab Source -> Default Output folder (set it to <ProjectName>/bin)

You could also check the .classpath file in your workspace which have to look like this (the path of the output folder is stored relative):

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
    <classpathentry kind="src" path="src"/>
    <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.6"/>
    <classpathentry kind="output" path="bin"/>
</classpath>
