Android Docx4J Gradle：重复类org.slf4j，尽管排除了它

我试图使用Docx4j库来读取用户选择的MS Word文件的内容（我试图通过以下示例进行安装：）。但是，我在读取MS Word文件时收到以下错误（我没有包括所有错误，但重复的类都属于

org.slf4j.*

）：

这似乎很奇怪，因为在我的build.gradle中，我在实现docx4j库时明确排除了

org.sl4j

下面是我的

build.gradle

在查看时，这提出了一个问题，您甚至需要libs/slf4j-android-1.6.1-RC1.jar做什么

org.slf4j

已经包含在内，它可以在没有这些Android绑定的Android上工作

pdfbox android

也差不多。当阅读这些需求时，几乎没有任何明显的实际尝试；因为根本没有Java/Kotlin代码。

在应用程序的build.gradle中添加以下行

configurations {
compile.exclude group: 'org.slf4j', module: 'slf4j-log4j12'
}

configurations.all {
    resolutionStrategy {
        force 'org.slf4j:slf4j-log4j12:1.7.25'
    }
}

您的用例正是Gradle功能的动机。有一个详细的解释

这篇博文的结果是一个错误

插件{
id（“dev.jacomet.logging capabilities”）版本“0.7.0”
}
记录能力{
enforceLog4J2（）//您可以像这样排除
org.slf4j:slf4j api:1.7.21
和所有其他从
org.docx4j:docx4j:3.3.0
获取冲突的对象

implementation('org.docx4j:docx4j:3.3.0') {
    exclude group: 'org.slf4j'
}

implementation('org.docx4j:docx4j:3.3.0') {
    ['org.apache.commons', 'commons-logging', 'org.sl4j', 'org.slf4j'].each {
            exclude group: "$it"
    }
}

或者你也可以像这样修改你的依赖关系

implementation('org.docx4j:docx4j:3.3.0') {
    exclude group: 'org.slf4j'
}

implementation('org.docx4j:docx4j:3.3.0') {
    ['org.apache.commons', 'commons-logging', 'org.sl4j', 'org.slf4j'].each {
            exclude group: "$it"
    }
}
