Question

我正在编辑一个使用gradle进行构建/依赖关系管理的开源软件包。我以前没用过gradle。

我想使用一些jackson方法，因此我将compile group: 'com.fasterxml.jackson.core', name: 'jackson-core', version: '2.7.5'添加到build.gradle文件中，并将import com.fasterxml.jackson.*;添加到我的项目中。

但是当我尝试使用./gradle shadowJar构建时，我收到以下错误：

Installing pre-commit hook for Unix/OS X
WARNING: jar does not create an executable jar. Use shadowJar instead.
:compileJava
/Users/mttjone/sw/builds/bixie-vanilla/src/main/java/bixie/checker/reportprinter/JSONReportPrinter.java:11: error: package com.fasterxml.jackson does not exist
import com.fasterxml.jackson.*;
^

...

4 errors
:compileJava FAILED

我认为你的问题与Gradle无关，只是纠正了你的代码。

包com.fasterxml.jackson真的存在吗？请注意，只有包com.fasterxml.jackson.databind或com.fasterxml.jackson.core存在，而对包com.fasterxml.jackson没有任何说明。这三个包绝对不相关且独立。没有像“子包”这样的东西。
