Exception in thread "main" java.lang.Error: Unresolved compilation problem:
And while I was trying run this code in Eclipse IDE it's telling me
当我尝试在 Eclipse IDE 中运行此代码时，它告诉我
declared package org.exist.examples.xmldb does not match the expected package
When I compile it it's throwing the error at Put.main(Put.java:27)
当我编译它时，它在 Put.main(Put.java:27) 处抛出错误

You are trying to run code that does not compile. Eclipse inserts bytecode that throws this error instead.
您正在尝试运行无法编译的代码。Eclipse 会插入引发此错误的字节码。
