gradle無需插件配置內嵌tomcat

//1.關閉IDEA中的gradle配置： Download external annotations for dependencies
否則會去下載annotations相關包，有時會出錯

// 2. build.gradle中倉庫與依賴配置
repositories {
    maven { url 'https://maven.aliyun.com/repository/jcenter/'}
    maven { url 'https://maven.aliyun.com/repository/central/' }

    mavenCentral()
    mavenLocal()
}
dependencies {
    testImplementation 'junit:junit:4.13'

    implementation "org.apache.tomcat.embed:tomcat-embed-core:9.0.44"
    implementation "org.apache.tomcat.embed:tomcat-embed-jasper:9.0.44"
    testImplementation "org.apache.tomcat.embed:tomcat-embed-core:9.0.44"
    testImplementation "org.apache.tomcat:tomcat-util:9.0.44"
　　// 實在不行可以先下載然后本地加載
　　// compile fileTree(dir: 'src/main/libs', includes: ['*.jar'])
}

/** 莫名其妙必須加上版本號才行，但是有的其他依賴不加也沒問題 **/
