Question

我正在尝试为Apache Kafka POC建立一个简单的gradle项目。请提出解决方法的建议。

构建时的堆栈跟踪

Root cause: org.gradle.internal.resolve.ArtifactNotFoundException: Could not find jms.jar (javax.jms:jms:1.1).
Searched in the following locations:
    https://repo1.maven.org/maven2/javax/jms/jms/1.1/jms-1.1.jar

这是用于项目的gradle文件

apply plugin: 'java-library'


repositories {

     mavenCentral()
}

dependencies {
    api 'org.apache.commons:commons-math3:3.6.1'

    implementation 'com.google.guava:guava:23.0'

    testImplementation 'junit:junit:4.12'

    compile(group: 'org.apache.kafka', name: 'kafka_2.10', version: '0.8.0') 

    compile 'org.apache.kafka:kafka-clients:0.10.2.0'
}

Answer 1

问题来自传递库 log4j-1.2.15 ，该传递库属于 zookeeper 传递库：

    +--- org.apache.kafka:kafka_2.10:0.8.0
|    +--- org.apache.zookeeper:zookeeper:3.3.4
|    |    +--- log4j:log4j:1.2.15
|    |    |    +--- javax.mail:mail:1.4
|    |    |    |    \--- javax.activation:activation:1.1
|    |    |    +--- javax.jms:jms:1.1
|    |    |    +--- com.sun.jdmk:jmxtools:1.2.1
|    |    |    \--- com.sun.jmx:jmxri:1.2.1
|    |    \--- jline:jline:0.9.94
|    |         \--- junit:junit:3.8.1

此 log4j 版本依赖于其他不在maven中央存储库中托管的库（请参见What happened to JMS 1.1 in Maven Central?）

因此您可以添加 jcenter（）存储库

repositories {
    jcenter()
    mavenCentral()
}

但是随后您将要排除的其他传递库还有其他问题：从传递依赖项中排除 log4j 或 jdmk 和 jmx 如下：

dependencies {
    api 'org.apache.commons:commons-math3:3.6.1'
    implementation 'com.google.guava:guava:23.0'
    testImplementation 'junit:junit:4.12'

    compile(group: 'org.apache.kafka', name: 'kafka_2.10', version: '0.8.0'){
        exclude group : "com.sun.jdmk"
        exclude group : "com.sun.jmx"

        // or simply exclude all  log4j:
        //  exclude group : "log4j"
    }
    compile 'org.apache.kafka:kafka-clients:0.10.2.0'
}
