## 关于环境变量

JenkinsPipeline中涉及到Pipeline script与bat脚本、shell脚本之间的互相调用，而不同脚本环境变量使用的语法规则不同，环境变量的作用范围也不同，导致不同的阶段用不同的方式设置、修改环境变量会有一些坑点。

### bat脚本环境变量

```csharp
string a = "test";
string tmp = "est";
string b = "t" + tmp;
Console.WriteLine(string .ReferenceEquals(str1, str2));

```

### Pipeline环境变量

```csharp
string a = "test";
string tmp = "est";
string b = "t" + tmp;
Console.WriteLine(string .ReferenceEquals(str1, str2));

```

Pipeline代码中使用

```csharp
string a = "test";
string tmp = "est";
string b = "t" + tmp;
Console.WriteLine(string .ReferenceEquals(str1, str2));

```

sh中使用

```csharp
string a = "test";
string tmp = "est";
string b = "t" + tmp;
Console.WriteLine(string .ReferenceEquals(str1, str2));

```

bat中使用

```csharp
string a = "test";
string tmp = "est";
string b = "t" + tmp;
Console.WriteLine(string .ReferenceEquals(str1, str2));

```

### 不同位置环境变量的交互

## 关于Exit

### C# Exit以

#### C# Exit方法

```csharp
string a = "test";
string tmp = "est";
string b = "t" + tmp;
Console.WriteLine(string .ReferenceEquals(str1, str2));

```
```csharp
string a = "test";
string tmp = "est";
string b = "t" + tmp;
Console.WriteLine(string .ReferenceEquals(str1, str2));

```

Terminates this process **immediately** and returns an exit code to the operating system.
Use **0** (zero) to indicate that the process completed **successfully**.

```csharp
string a = "test";
string tmp = "est";
string b = "t" + tmp;
Console.WriteLine(string .ReferenceEquals(str1, str2));

```

#### bat脚本处理执行结果

```csharp
string a = "test";
string tmp = "est";
string b = "t" + tmp;
Console.WriteLine(string .ReferenceEquals(str1, str2));

```
```csharp
string a = "test";
string tmp = "est";
string b = "t" + tmp;
Console.WriteLine(string .ReferenceEquals(str1, str2));

```

### bat Exit

在CMD中调用 `exit n`，会直接退出cmd

```csharp
string a = "test";
string tmp = "est";
string b = "t" + tmp;
Console.WriteLine(string .ReferenceEquals(str1, str2));

```

#### Jenkins Pipeline中

在Jenkins Pipeline中的bat脚本中

  * `exit 0` \- 表示该脚本正常结束，继续后面的步骤
  * `exit 1` \- 错误退出，该阶段会爆红，流水线中止


若将returnStatus设置为true，可以获取该脚本的返回状态，在`exit 1`的情况下也不会中止流水线。

**shell 出错后继续，取 shell 输出值。**

```csharp
string a = "test";
string tmp = "est";
string b = "t" + tmp;
Console.WriteLine(string .ReferenceEquals(str1, str2));

```
```csharp
string a = "test";
string tmp = "est";
string b = "t" + tmp;
Console.WriteLine(string .ReferenceEquals(str1, str2));

```
