What different breakpoint icons mean in Eclipse?
提问by Fixpoint
When working with breakpoints in Eclipse I sometimes notice that they have different icons / annotations (markers on left sidebar). Sometimes it's just a blue ball, sometimes it has a checkmark on it and sometimes it is crossed. What do all these annotations mean?
在 Eclipse 中使用断点时，我有时会注意到它们有不同的图标/注释（左侧边栏上的标记）。有时它只是一个蓝色的球，有时上面有一个复选标记，有时它被交叉了。所有这些注释是什么意思？

- blue ball: regular breakpoint, active (possibly with a hit count set)
- empty ball (i.e. white): breakpoint has been disabled (remove checkmark in the breakpoint view, or
disablein context menu) - diagonal line through breakpoint: all breakpoints have been disabled (button
skip all breakpointsin breakpoint view) - question mark next to breakpoint: a condition is active for this breakpoint (look under properties of the breakpoint)
- 蓝球：常规断点，活动（可能设置了命中次数）
- 空球（即白色）：断点已被禁用（在断点视图或
disable上下文菜单中删除复选标记） - 通过断点的对角线：所有断点都已禁用（
skip all breakpoints断点视图中的按钮） - 断点旁边的问号：此断点的条件处于活动状态（查看断点的属性）

The tick means that the breakpoint has been successfully set. I think it may only appear when you're doing remote debugging; when you add a breakpoint, it starts out as a plain ball, but once the JPDA agent in the remote system has been told about it, and has confirmed it's set, then it gets a tick.
打勾表示断点设置成功。我认为它可能只有在您进行远程调试时才会出现；当你添加一个断点时，它开始是一个普通的球，但是一旦远程系统中的 JPDA 代理被告知它并确认它已设置，那么它就会得到一个滴答声。

I have created an example code with explanation inline.
我已经创建了一个带有内联解释的示例代码。
public class Breakpoints {
int field1; // watchpoint - suspend when field1 is read
int field2; // watchpoint - suspend when field1 is written
int field3; // watchpoint - suspend when field1 is read or written
public void method() {
int x;
x = 10; // suspend before this line is executed
x = 11; // same as above but this breakpoint is temporarily disabled
for (int i = 0; i < 100; i++) {
x = i; // conditional breakpoint - suspend when i==5
}
}
}
Once you select Skip All Breakpointsin the Breakpoints view (Window | Show Viev | Debug | Breakpoints), all the icons become diagonally struck through like this:
Skip All Breakpoints在 Breakpoints 视图 ( Window | Show Viev | Debug | Breakpoints) 中选择后，所有图标都变成对角线，如下所示：

Adding to earlier answers. The small white cover a green ballicon means that the breakpoint is at the class level.
添加到先前的答案。绿色球图标上的小白色c表示断点位于类级别。

I think answer given by @sleske is explaining all things except for :
我认为@sleske 给出的答案解释了除以下内容之外的所有内容：
Blue Ball with Tick: Breakpoint is successfully set because Your Source code matches with the Byte Code and debug control will reach there.
Blue Ball with Tick: Breakpoint 成功设置，因为您的源代码与字节代码匹配，调试控制将到达那里。
Only Blue Ball: Source code differs from Byte code (May be you are running a older Snapshot of code). Control will never reach at this breakpoint. You will have to update your JARs to get control to these breakpoints.
只有蓝球：源代码与字节代码不同（可能您正在运行旧的代码快照）。控制永远不会到达这个断点。您必须更新 JAR 才能控制这些断点。

If you see a "T" on the blue ball, It means a triggering point for remote debugging 
如果看到蓝球上有一个“T”，表示远程调试的触发点
