您没有说明如何使用Maven，但我怀疑您只是为您的应用程序生成JAR文件。
您应该使用Maven GAE plugin并在POM文件中指定相关的“以太”库作为依赖项。
（注意：我没有亲身经历，但是插件文档暗示它将为您处理依赖关系。）

您的java类路径似乎存在问题。丢失的罐子似乎是这个：
http://mvnrepository.com/artifact/org.sonatype.aether/aether-api/1.13.1
具体来说，这是jar：http://repo1.maven.org/maven2/org/sonatype/aether/aether-api/1.13.1/aether-api-1.13.1.jar
将该jar放入类路径中。它包含org.sonatype.aether.RepositorySystem类。
