spring-security-rest和芭乐之间的间接jar冲突导致NoSuchMethod错误

Question

我使用grails 3.1.16

build.gradle：

dependencies {
    compile "com.google.guava:guava:18.0"
    compile "org.grails.plugins:spring-security-rest:2.0.0.M2"
}

在运行此代码时：

   private LoadingCache<String, Boolean> attempts

    @PostConstruct
    void init() {
        Integer time = ApplicationContextHolder.getProperty(ApplicationContextHolder.config.time)
        attempts = CacheBuilder.newBuilder()
                .expireAfterWrite(time, TimeUnit.MINUTES)
                .build({ 0 } as CacheLoader)
    }

我收到以下错误：

Caused by: java.lang.NoSuchMethodError: com.google.common.base.Platform.systemNanoTime()J
        at com.google.common.base.LocalCache(Ticker.java:60)
        at com.google.common.cache.LocalCache$Segment.put(LocalCache.java:2827)
        at com.google.common.cache.LocalCache.put(LocalCache.java:4149)
        at com.google.common.cache.LocalCache$LocalManualCache.put(LocalCache.java:4754)
        at com.google.common.cache.Cache$put.call(Unknown Source)

运行依赖报告后，我发现这个问题是由Spring Security REST插件的依赖引起的：( com.google.guava:guava-base:r03) -具有相同的包名"com.google.common.base“和没有这种方法systemNanoTime()的Platform.class。

|    +--- org.grails.plugins:spring-security-rest:2.0.0.M2
|    |    +--- com.google.guava:guava-io:r03
|    |    |    +--- com.google.guava:guava-annotations:r03
|    |    |    \--- com.google.guava:guava-base:r03
|    |    |         \--- com.google.guava:guava-annotations:r03

有什么办法来解决这个问题吗？

Answer 1

步骤1.请检查更新的依赖项(issue may be reported)：

dependencies {
    compile 'org.grails.plugins:spring-security-rest:2.0.0.RC1'
    compile 'com.google.guava:guava:24.0-jre'
}

您可以检查spring-security-rest documentation和repo，以及芭乐documentation和repo

或

步骤2.

compile("org.grails.plugins:spring-security-rest:2.0.0.RC1") {
            excludes([group: 'com.google.guava:guava'])
}

或

步骤3.在build.gradle中，您可以从JAR文件中排除已编译的类：

jar {
 exclude "com/google/guava/**/**"
}

或者您可以参考grails documentation

Answer 2

你试过了吗？

dependencies {
    compile "com.google.guava:guava:18.0"
    compile ("org.grails.plugins:spring-security-rest:2.0.0.M2") {
        exclude module: 'guava-base'

        // can also be specified with group
        // exclude group: 'com.google.guava', module: 'guava-base'
    }
}

这将从spring-security-rest中排除guava-base的传递依赖项。
