我有一个class compare{
private $array1;
private $array2;
public function __construct($mile1, $mile2){
$this->array1 = $mile1->milearray;
$this->array2 = $mile2->milearray;
}
public function comparemile(){
// code that compares $this->$array1 and $this->$array2
}
}
项目和两个parent / child-1项目。在我的磁盘上，所有共享相同的父目录：
child-2为了尽量减少工作异常，请考虑以下/my-project
/parent
/child-1
/child-2

项目中，我故意不包括以下模块定义：
parent这样做的原因是我想独立于子项目构建父项。每当父项目更改时，Jenkins都会自动重建所有子项目。
在我的开发机器上，如果我可以重建整个项目，这将很有用。也就是说，首先<modules>
<module>child-1</module>
<module>child-2</module>
</modules>
，然后是parent和child-1。我可以在所有3个目录中调用child-2，但这很麻烦。请注意，在实际情况下，有更多的mvn compile项目，并且它们之间存在依赖性。因此，我将必须在项目依赖关系图中构建与它们的拓扑排序相对应的每个child项目。
所以我考虑过引入一个child项目，如下所示：
builder/my-project
/parent
/child-1
/child-2
/builder
现在，当我在<?xml version='1.0' encoding='UTF-8'?>

</modules>
</project>
目录中调用mvn compile时，我得到：
builder那是为什么？如何解决？我对这个[ERROR] [ERROR] Some problems were encountered while processing the POMs:

项目的想法完全可能吗？
