java - 无法执行目标org.codehaus.mojo :exec-maven-plugin:1. 5.0:exec

Question

三周前，我已经完成了Web应用程序的工作。一切运行都没有问题。

现在，三个星期后，什么都没有更改(!!!)，我想再次运行该应用程序，但是这次我收到以下错误消息:

 An error occurred while parsing the server response. Error message is: Provider org.glassfish.json.JsonProviderImpl not found

Answer 1

我从您的pom.xml中获取了依赖项进行测试。

我创建了pom.xml。

<project xmlns="http://maven.apache.org/POM/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <groupId>com.michael</groupId>
    <artifactId>optimizer</artifactId>
    <version>1.0-SNAPSHOT</version>
    <dependencies>
        <dependency>
            <groupId>org.mongodb</groupId>
            <artifactId>mongo-java-driver</artifactId>
            <version>3.4.1</version>
        </dependency>
        <dependency>
            <groupId>javax</groupId>
            <artifactId>javaee-web-api</artifactId>
            <version>7.0</version>
        </dependency>
    </dependencies>
</project>

我检查了它是否包含用于此问题的必要 jar 。

我使用了maven命令: mvn dependency:tree。使用此命令，您可以查看使用了哪些jar和从属jar。



这些-> javax.json和 javax.json-api工件丢失。

在 pom.xml中添加此依赖项以忽略此错误:

<!-- This jar provides the interfaces -->
<!-- This may be optional as javaee-web-api contains JsonProvider.class -->
<!-- But still I will recommend to add this explicitly for you to be at safer side -->
<dependency>
    <groupId>javax.json</groupId>
    <artifactId>javax.json-api</artifactId>
    <version>1.0</version> 
</dependency> 
<!-- This jar provides the implementation of this interfaces
<dependency>
    <groupId>org.glassfish</groupId>
    <artifactId>javax.json</artifactId>
    <version>1.1.4</version>
</dependency>

注意: javax.json-api实现由 javax.json完成。
