删除gwt开发依赖项时无法运行GAE测试（java.lang.NoClassDefFoundError:org/mortbay/xml/XmlParser）

我正在试图找出如何修复此错误，有人说是关于

httpcore

depdency的：

java.lang.NoSuchFieldError: DEF_CONTENT_CHARSET
    at com.jayway.restassured.config.EncoderConfig.<init>(EncoderConfig.java:48)
    at com.jayway.restassured.config.RestAssuredConfig.<init>(RestAssuredConfig.java:41)
    at com.jayway.restassured.RestAssured.<clinit>(RestAssured.java:423)

更新：

显然，这是由GWT依赖性引起的：

  <dependency>
      <groupId>com.google.gwt</groupId>
      <artifactId>gwt-dev</artifactId>
      <version>${version.gwt}</version>
      <scope>test</scope>
      <exclusions>
          <exclusion>
              <groupId>org.apache.httpcomponents</groupId>
              <artifactId>httpcore</artifactId>
          </exclusion>
      </exclusions>
  </dependency>

---

解决方案是确保不要选择GWT类：

  <dependency>
      <groupId>com.jayway.restassured</groupId>
      <artifactId>rest-assured</artifactId>
      <version>2.4.0</version>
  </dependency>
  <dependency>
      <groupId>com.google.gwt</groupId>
      <artifactId>gwt-dev</artifactId>
      <version>${version.gwt}</version>
      <scope>test</scope>
  </dependency>

com.jayway.restassed
放心
2.4.0
com.google.gwt
gwt开发
${version.gwt}
测试

有了这个命令后，测试工作正常。

如果显示stacktrace，那么拥有完整的stacktrace将很有帮助，不仅有experts。。此外，pom文件也会很有帮助。@khmarbaise我发现了这个问题
