防止Flyway Maven插件下载旧的slf4j jars

Question

当我运行flyway maven插件时，它首先下载版本为1.5.6的slf4j jars:

[INFO] ------------------------------------------------------------------------
Downloading: http://repo1.maven.org/maven2/org/slf4j/slf4j-jdk14/1.5.6/slf4j-jdk14-1.5.6.pom
Downloaded: http://repo1.maven.org/maven2/org/slf4j/slf4j-jdk14/1.5.6/slf4j-jdk14-1.5.6.pom (2 KB at 21.3 KB/sec)
Downloading: http://repo1.maven.org/maven2/org/slf4j/slf4j-parent/1.5.6/slf4j-parent-1.5.6.pom
Downloaded: http://repo1.maven.org/maven2/org/slf4j/slf4j-parent/1.5.6/slf4j-parent-1.5.6.pom (8 KB at 154.7 KB/sec)

这严重破坏了我的Spring web应用程序，因为我在那里使用的是slf4j的1.7.2版本，当我重新启动它时，它变得混乱。

我该如何防止这种情况？我尝试过在我的pom中添加排除项.xml：

<groupId>com.googlecode.flyway</groupId>
                <artifactId>flyway-maven-plugin</artifactId>
                <version>2.0.3</version>
                <exclusions>
                    <exclusion>
                        <groupId>org.slf4j</groupId>
                        <artifactId>slf4j-log4j12</artifactId>
                    </exclusion>
                    <exclusion>
                        <groupId>org.slf4j</groupId>
                        <artifactId>slf4j-api</artifactId>
                    </exclusion>
                    <exclusion>
                        <groupId>org.slf4j</groupId>
                        <artifactId>jcl-over-slf4j</artifactId>
                    </exclusion>
                </exclusions>

但这仍然会发生。

更新：这导致的是以下错误，当我使用Intellij 12进行构建时：

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/Users/tom/Library/Caches/IntelliJIdea12/tomcat/Unnamed_incrowdnow/work/Catalina/localhost/_/WEB-INF/lib/slf4j-jdk14-1.5.6.jar!/org/slf4j/impl/StaticLoggerBinder.class]

更新:mvn依赖项的输出:tree-dver base-din includes = org . slf4j

Answer 1

FLyway下载slf4j依赖项，如果您的应用程序使用1.7.x或1.6.x版本，则会遇到此问题，因为Flyways下载了1.5.3版本的slf4j nop和1.5.6版本的slf4j-jdk14。在eclipse中，您可以在pom.xml的依赖层次结构下看到

为了摆脱这种情况，请添加以下所有排除，您就完成了

        <exclusions>
            <exclusion>
                <groupId>org.slf4j</groupId>
                <artifactId>slf4j-api</artifactId>
            </exclusion>
            <exclusion>
                <groupId>org.slf4j</groupId>
                <artifactId>log4j-over-slf4j</artifactId>
            </exclusion>
            <exclusion>
                <groupId>org.slf4j</groupId>
                <artifactId>jcl-over-slf4j</artifactId>
            </exclusion>
            <exclusion>
                <groupId>org.slf4j</groupId>
                <artifactId>slf4j-nop</artifactId>
            </exclusion>    
            <exclusion>
                <groupId>org.slf4j</groupId>
                <artifactId>slf4j-jdk14</artifactId>
            </exclusion>                
        </exclusions>    

Answer 2

我有类似的问题，并通过使用flyway-core依赖项而不是flyway-maven-plugin依赖项来解决它。

Answer 3

飞道专家插件 2.0.3 和飞道核心 2.0.3 都不依赖于 slf4j。检查依赖项。问题一定来自其他地方。
