在官网上下载了spring security oauth2.0的例子，但是运行samples\oauth2\里的sparklr项目时，报错如下：
[WARNING] The requested profile "spring" could not be activated because it does not exist.
[ERROR] Failed to execute goal on project sparklr2: Could not resolve dependencies for project org.springframework.security.oauth:sparklr2:war:2.3.5.BUILD-SNAPSHOT: Failed to collect dependencies at org.springframework.security.oauth:spring-security-oauth2:jar:2.3.5.BUILD-SNAPSHOT: Failed to read artifact descriptor for org.springframework.security.oauth:spring-security-oauth2:jar:2.3.5.BUILD-SNAPSHOT: Failure to find org.springframework.security.oauth:spring-security-oauth-parent:pom:2.3.5.BUILD-SNAPSHOT in http://repo.spring.io/libs-snapshot was cached in the local repository, resolution will not be reattempted until the update interval of spring has elapsed or updates are forced -> [Help 1]

上面的报错意思很简单，就是找不到spring-security-oauth2:jar:2.3.5.BUILD-SNAPSHOT这个jar包，但是不应该啊，直接从官网下的怎么可能找不到jar包，后来看到snapshot的后缀，心想是不是还是测试阶段，并没有放到maven仓库里，所以找不到。于是在下载的工程里找到了spring-security-oauth2这个项目。
这就简单了，把这个项目导入进来后手动打成jar包。再把jar包加到本地maven仓库即可。注意：这里不能直接复制到本地maven仓库的对应目录里，这样工程里还是不认的。必须用maven命令才行。命令如下：
mvn install:install-file -Dfile=E:\downloads\spring-security-oauth-master\spring-security-oauth-master\spring-security-oauth2\target\spring-security-oauth2-2.3.5.BUILD-SNAPSHOT.jar -DgroupId=org.springframework.security.oauth -DartifactId=spring-security-oauth2 -Dversion=2.3.5.BUILD-SNAPSHOT -Dpackaging=jar
再运行工程就不会报上面找不到jar包的错了。
