创建自定义处理器 apache nifi 时出错 [英] Error during the creating of custom processors apache nifi

问题描述

我尝试使用 mvn clean package 命令使用 NiFi 自定义处理器构建我的包，我得到以下输出:

I tried to build my package with NiFi custom-processor using mvn clean package command and I got the following output:

有人知道如何处理与 maven-compiler-plugin:3.8.1:testCompile 相关的问题吗?我使用 Apache NiFi 版本 1.13.2 并且 mvn install -DskipTests 没有改变任何东西.

Does anybody know how to handle this issue related to the maven-compiler-plugin:3.8.1:testCompile, please ? I use Apache NiFi version 1.13.2 and mvn install -DskipTests does not change anything.

推荐答案

出现这个错误的原因是 pom 的 url 无法访问.

The reason for this error is that the pom's url is not accessable.

目前，groovy-eclipse-batch-2.5.4-01.pom 链接被禁止.(dl.bintray.com/groovy/maven/org/codehaus/groovy/groovy-eclipse-batch/2.5.4-01/groovy-eclipse-batch-2.5.4-01.pom)

Currently, groovy-eclipse-batch-2.5.4-01.pom link is forbidden.(dl.bintray.com/groovy/maven/org/codehaus/groovy/groovy-eclipse-batch/2.5.4-01/groovy-eclipse-batch-2.5.4-01.pom)

检查 groovy-eclipse-batch 是否存在于您的 Maven 存储库中.或者只是在 mvnrepository.com 上找到一个有效的版本并使用它.(https://mvnrepository.com/artifact/org.codehaus.groovy/groovy-eclipse-batch)

Check if groovy-eclipse-batch exists in your maven repository. Or just find a valid version on mvnrepository.com and use it. (https://mvnrepository.com/artifact/org.codehaus.groovy/groovy-eclipse-batch)

例如，将 groovy-eclipse-batch 的版本更改为 2.5.6-01.

For example, change version of groovy-eclipse-batch to 2.5.6-01.

尝试将以下内容添加到捆绑项目的父 pom 中:

Try adding the following to your parent pom for the bundle project :

<build>
    <plugins>
        <plugin>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.8.1</version>            
            <configuration>
                <source>1.8</source>
                <target>1.8</target>
                <encoding>UTF-8</encoding>
            </configuration>                        
            <dependencies>
                <dependency>
                    <groupId>org.codehaus.groovy</groupId>
                    <artifactId>groovy-eclipse-batch</artifactId>
                    <version>2.5.6-01</version>
                </dependency>
            </dependencies>                 
        </plugin>
    </plugins>
</build>

在添加依赖之前:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.1:testCompile (groovy-tests) on project mytest: Execution groovy-tests of goal org.apache.maven.plugins:maven-compiler-plugin:3.8.1:testCompile failed: Plugin org.apache.maven.plugins:maven-compiler-plugin:3.8.1 or one of its dependencies could not be resolved: Failed to collect dependencies at org.apache.maven.plugins:maven-compiler-plugin:jar:3.8.1 -> org.codehaus.groovy:groovy-eclipse-batch:jar:2.5.4-01: Failed to read artifact descriptor for org.codehaus.groovy:groovy-eclipse-batch:jar:2.5.4-01: Could not transfer artifact org.codehaus.groovy:groovy-eclipse-batch:pom:2.5.4-01 from/to bintray (https://dl.bintray.com/groovy/maven): Access denied to: https://dl.bintray.com/groovy/maven/org/codehaus/groovy/groovy-eclipse-batch/2.5.4-01/groovy-eclipse-batch-2.5.4-01.pom -> [Help 1]

添加依赖后:
