我正在进行Jenkins插件开发。我有一个特殊的工作类型，在保存项目时创建自由风格项目。
例如：Jenkins>新建项目/新工作>输入名称（如"特殊项目"），然后单击"构建特殊项目"单选按钮>单击保存。单击保存后，将使用以下代码创建自由风格项目（子项目）：
FreeStyleProject childProject = Jenkins.getInstance().createProject(FreeStyleProject.class,"newName");
FreeStyleProject childProject1 = Jenkins.getInstance().createProject(FreeStyleProject.class,"newName1");
当我的"特殊项目"得到构建时，我想触发这些childProject，childProject1作业（比如通过计时器或单击"立即构建"）
我尝试了下面的代码，但出现了异常。

此外，我还浏览了MultiJob Jenkins插件https://wiki.jenkins-ci.org/display/JENKINS/Multijob+插件。但是，所有子作业都是通过单独的线程执行的，而不是通过执行器执行的。
有人能在这个问题上帮我吗？
提前谢谢！
Christopher先生的回答：
创建一个新的Cause类，如下所示，并使用相同的类代替Anonymous class:
public static class SpecialCause extends Cause {
private String note;
public SpecialCause (String note) {
this.note = note;
}
@Override
public String getShortDescription() {
if(note != null) {
return note;
} else {
return "Parent build triggered this build ";
}
}
@Override
public boolean equals(Object o) {
return o instanceof SpecialCause;
}
@Override
public int hashCode() {
int hash = 5;
hash = 83 * hash + (this.note != null ? this.note.hashCode() : 0);
return hash;
}
}
