#### 原始内容：
```
public ScmClientBuilder withCommType(ConfCommType commType) {
this.commType = commType;
return this;
}
public ScmClientBuilder withListeners(ScmEventListener... listeners) {
this.listeners = listeners;
return this;
}
```
#### 目标内容：
```
public ScmClientBuilder withCommType(ConfCommType commType) {
if (nonNull(commType)) {
this.commType = commType;
}
return this;
}
public ScmClientBuilder withListeners(ScmEventListener... listeners) {
if (nonNull(listeners)) {
this.listeners = listeners;
}
return this;
}
```
查找正则：
```
this.([0-9a-zA-Z]+) = ([0-9a-zA-Z]+);
```
