未能執行目標 org.codehaus.mojo:exec-maven-plugin:1.5.0:exec

Question

三周前，我完成了 web 應用程序的工作。 一切都運行沒有問題。

現在，三周后，沒有任何改變（，：！），我想再次運行應用程序，但這次我收到以下錯誤消息：

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

Answer 1

我從您的 pom.xml 中獲取了依賴項進行測試。

我創建了我的 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>

我檢查了它是否包含此問題所需的 jars。

我使用了 maven 命令： mvn dependency:tree 。 使用此命令，可以查看使用了哪些 jars 和依賴的 jars。

這些 -> javax.json & javax.json-api工件丟失。

在pom.xml中添加此依賴項以忽略此錯誤：

<!-- 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的實現由javax.json完成。

Answer 2

您正在使用javaee-web-api依賴項，它具有javax.json.spi.JsonProvider.class class 文件而不是實際實現。

您需要有JsonProvider的實際實現。 所以添加javax.json依賴。 它具有JsonProvider實現 class org.glassfish.json.JsonProviderImpl.class 。

<!-- https://mvnrepository.com/artifact/org.glassfish/javax.json -->
<dependency>
    <groupId>org.glassfish</groupId>
    <artifactId>javax.json</artifactId>
    <version>1.1.4</version>
</dependency>

Answer 3

@Anish B.：javax.json 依賴項將 JsonProvider 實現 class 作為依賴項（如 Code_Mode 所指出的那樣）......但是（如 assylias 所指出的那樣），實際上甚至不需要 javax.Z466DEEC76ECDF35FCA6D385DZ 依賴項作為應用程序應該提供這種依賴。
