通过jboss 5.1.1进行部署时,我遇到了以下错误:

在过去的几个月里，我们的快照备份量增加了，因此我们在亚马逊 EC2 上的每月账单增加了。现在我想删除一些旧的 EC2 快照。那么问题来了：
如何使用 EC2 命令行工具查找从单个卷 ID 创建的所有快照？ 我试过 ec2-describe-snapshots 但这列出了所有的快照。我们有很多快照，我很难将它们一一记录下来。
I could not figure out how to command Jenkins to upload an APK to Testfairy. I know that Testfairy has an API for this, see the link below:
http://blog.testfairy.com/how-to-upload-an-app-to-testfairy-via-api/
I'm new to this, how do I use the API?
我开发了一个小应用程序GPUImage.我设置了一个过滤器GPUImageView并更改了图像,但是如何删除过滤器以查看真实图像？
我使用jaxb2-maven-plugin的xjc目标从一组 xsd 文件生成 Java 类。
一个最小的、完整的和可验证的例子是一个带有以下 pom.xml 文件的 Maven 项目：

32 (defn my-max
33 ([list]
34 (if (empty? list)
35 -1
36 (my-max (pop list) (first list))) ; recursive call

43 (my-max (pop list) high))
44 )
45
46 (println (my-max '(1 2 3)))
如您所见,我对包含1,2和3的列表进行了硬编码,其中应返回3个.运行代码时收到错误:

public class StreamObjectCreator {
public List<X> createObjects(Integer... s) {
return Arrays.stream(s).map(X::new).collect(Collectors.toList());
}
private static class X {

现在,考虑以下枚举Y:
private static enum Y {
VALUE_1(2), VALUE_2(1);
private int i;
private Y(int i) {
this.i = i;
}
public int getI() {
return i;
}
}
我想做类似的事情并返回以下列表:
[VALUE_1,VALUE_1,VALUE_2]
换句话说,i每个枚举值的出现.
使用"旧的"Java方式,它可以像这样实现.
List<Y> createEnumList() {
List<Y> list = new ArrayList<Y>();
for (Y …
