常用Maven Repository

	Repository
oracle	https://maven.oracle.com
jboss	https://repository.jboss.org/nexus/content/groups/public/
	https://repository.jboss.org/nexus/content/repositories/fs-releases
redhat	https://maven.repository.redhat.com/ga/

说明：访问Oracle Repository需要账号，配置步骤如下：

1. 在.m2下创建文件settings-security.xml来保存master密码

使用下面的命令生成master密码：

mvn -encrypt-master-password <any_master_password>
或
mvn -emp <any_master_password>

settings-security.xml内容如下：

<settingsSecurity>
  <master>{By8wW7YcTxAHof0MF4Z3wPKboywhGJvxHD9m0NvHA2U=}</master>
</settingsSecurity>

2. 配置settings.xml

使用下面命令加密用户密码：

mvn -encrypt-password <any_master_password>
或
mvn -ep <any_master_password>

配置用户和repository：

<servers>
  <server>
    <id>maven.oracle.com</id>
    <username>[email protected]</username>
    <password>{pnwmhVnzdM8H3UAneUKLmaHGZCoaprbMQ/Ac5UktvsM=}</password>
    <configuration>
      <basicAuthScope>
        <host>ANY</host>
        <port>ANY</port>
        <realm>OAM 11g</realm>
      </basicAuthScope>
      <httpConfiguration>
        <all>
          <params>
            <property>
              <name>http.protocol.allow-circular-redirects</name>
              <value>%b,true</value>
            </property>
          </params>
        </all>
      </httpConfiguration>
    </configuration>
  </server>
</servers>

<profiles>
  <profile>
    <id>main</id>
    <activation>
      <activeByDefault>true</activeByDefault>
    </activation>
    <repositories>
      <repository>
        <id>maven.oracle.com</id>
        <url>https://maven.oracle.com</url>
        <layout>default</layout>
        <releases>
          <enabled>true</enabled>
        </releases>
      </repository>
    </repositories>
  </profile>
</profiles>

3. 配置POM依赖

<dependency>
    <groupId>com.oracle.jdbc</groupId>
    <artifactId>ojdbc6</artifactId>
    <version>11.2.0.4</version>
    <exclusions>
        <exclusion>
            <groupId>*</groupId>
            <artifactId>*</artifactId>
        </exclusion>
    </exclusions>
</dependency>
