Question

我尝试从Spring's guide设置Spring Roo，但我收到以下错误。我怀疑它与this bug概述的Java 8兼容性有关，但我对如何继续解决此问题表示阻止。

以下是我的错误示例：

另外，我使用的是Java 8：

[lucas-ThinkPad-W520]/home/lucas$ java -version
java version "1.8.0_20"
Java(TM) SE Runtime Environment (build 1.8.0_20-b26)
Java HotSpot(TM) 64-Bit Server VM (build 25.20-b23, mixed mode)

这是我的Maven版本：

[lucas-ThinkPad-W520]/home/.../springsource/spring-roo-1.2.5.RELEASE$ mvn -version
Apache Maven 3.0.5
Maven home: /usr/share/maven
Java version: 1.8.0_20, vendor: Oracle Corporation
Java home: /usr/lib/jvm/java-8-oracle/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "3.13.0-35-generic", arch: "amd64", family: "unix"

如果重要的话，我正在运行Ubuntu 14.04。有关如何进行的任何建议都会有所帮助。另外，如果可能的话，我更愿意继续使用Java 8。

希望这有助于某人，但我终于明白了 - 详细信息发布在错误报告页面上的论坛中：http://forum.spring.io/forum/spring-projects/roo/106193-error-staring-the-roo-shell

我下载了Apache Felix Framework Distribution here，并且从felix发行版中，我将文件bin/felix.jar移动到spring-roo.1.2.5.RELEASE/bin。在那之后，一切正常！

希望这有助于某人！

实际上，它可能需要完整的JDK ...您正在使用JRE。

自动更新Java后会发生此错误，这会意外将Java切换到JRE。

（以及您提供的链接中的事件... JDK / JRE的原因是第一个sugestino）

无法运行Spring Roo shell - ＆＃34;无法解决..缺少需求.. package = javax.xml ...＆＃34;
