java 缺少依赖关系 org.json:json:jar

Question

提问by SimonaC

I have a problem with the project I am working on. Until Tuesday everything seemed to be fine when I was building and running my project. Today I wanted to run the project and I received this error message:

我正在处理的项目有问题。直到周二，当我构建和运行我的项目时，一切似乎都很好。今天我想运行这个项目，我收到了这个错误信息：

  [ERROR] [ERROR] Some problems were encountered while processing the POMs:
    [ERROR] 'dependencies.dependency.version' for org.json:json:jar is missing. @ 
    line 57, column 21

After I added the version, the build is now failing due to this exception:

添加版本后，由于此异常，构建现在失败：

It looks like You have more than one org.json:jsondependency on your classpath.

看起来您org.json:json对类路径有不止一种依赖。

Looking at it:
org.springframework.boot:spring-boot-starter-testdepends on
com.jayway.jsonpath:json-pathwhich in turn brings
org.json:jsonwhich is much older than your version (v. 20140107)

看看它：
org.springframework.boot:spring-boot-starter-test取决于
com.jayway.jsonpath:json-path哪个反过来带来
org.json:json比你的版本更旧的版本（v. 20140107）

You could try excluding this transitive dependency from spring-boot-starter-test:

您可以尝试从spring-boot-starter-test以下内容中排除此传递依赖项：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
    <scope>test</scope>
    <exclusions>
        <exclusion>
            <groupId>org.json</groupId>
            <artifactId>json</artifactId>
        </exclusion>
    </exclusions>
</dependency>

... but it's possible that there is something within json-pathwhich depends on something from the older jsonlibrary, which is no longer in the newer version, so proceed with caution and test everything thoroughly.

...但有可能其中的某些json-path内容依赖于较旧的json库中的某些内容，而该库不再是较新版本中的内容，因此请谨慎行事并彻底测试所有内容。

There is also a chance that something else brings org.json:json.

也有可能是其他东西带来的org.json:json。

To verify, please run mvn dependency:treeand search in the produced output for org.json:json.

要验证，请运行mvn dependency:tree并在生成的输出中搜索org.json:json.

Spring Boot 2.0 released on 1 Mar 2018. Before that the latest RELEASE version for Spring Boot was 1.5.x.

Spring Boot 2.0 于 2018 年 3 月 1 日发布。在此之前，Spring Boot 的最新 RELEASE 版本是 1.5.x。

Set the Spring Boot version to 1.5.12.RELEASE and try again:

将 Spring Boot 版本设置为 1.5.12.RELEASE 并重试：

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.5.12.RELEASE</version>

    <relativePath />
</parent>

The version definition (<version>RELEASE</version>) of your spring boot parent is incorrect.

<version>RELEASE</version>您的 spring 引导父级的版本定义 ( ) 不正确。

The correct way to define a spring boot parent is -

定义 spring boot 父级的正确方法是 -

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.0.0.RELEASE</version>

    <relativePath />
</parent>
