阴影罐缺少依赖项中的某些Vert.x类

我已经使用Kotlin协程扩展成功创建了一个具有很少数量顶点的阴影罐,并且能够通过vertx run命令行运行它们,同时指定了我jar的路径,除了在启动时会创建telnet的顶点外壳除外:

我的项目是使用Gradle(Kotlin DSL)构建的

这些是我的vert.x依赖项:

io.vertx:vertx-core
io.vertx:vertx-lang-kotlin
io.vertx:vertx-lang-kotlin-coroutines
io.vertx:vertx-shell
io.vertx:vertx-auth-shiro
io.vertx:vertx-tcp-eventbus-bridge

我的影子罐任务配置如下:

tasks.withType<com.github.jengelman.gradle.plugins.shadow.tasks.ShadowJar> {
    classifier = "fat"
    isPreserveFileTimestamps = false
    isReproducibleFileOrder = true
    minimize()
    manifest {
        attributes["Main-Verticle"] = vertx.mainVerticle
    }
    mergeServiceFiles {
        include("META-INF/services/io.vertx.core.spi.VerticleFactory")
    }
}

似乎不是minimize()的问题,但重要的是,如果我从main函数以编程方式部署该vertver,则evrything可以正常工作,并且我获得了telnet shell。

也许我在影子jar任务的清单配置中缺少某些内容?

1 个答案:

答案 0 :(得分:0)

我在HoconProcessor(here)上遇到了类似的问题,但与此同时,与此相关的还有GraphiQLHandlerOptions类,我导入了不推荐使用的版本(look),导致该类将以相同的名称包含在jar中,但预期使用时会抛出TelnetTermOptions

由于{{1}}也是这样的选项类,因此也许最近遭受了类似的弃用。希望这会有所帮助/启发。
