maven deploy的两点

1 第一个问题

执行mvn clean deploy失败，报错如下：

Caused by: org.apache.maven.plugin.MojoExecutionException: Failed to deploy artifacts: Could not transfer artifact com.cainiao:nballowance-client:jar:1.0.4-snapshot from/to releases (http://mvnrepo.xxx.com/mvn/releases): Failed to transfer file: http://mvnrepo.xxx.com/mvn/releases/com/cainiao/nballowance-client/1.0.4-snapshot/nballowance-client-1.0.4-snapshot.jar. Return code is: 401, ReasonPhrase: Unauthorized.        at org.apache.maven.plugin.deploy.DeployMojo.execute(DeployMojo.java:193)        at org.apache.maven.plugin.DefaultBuildPluginManager.executeMojo(DefaultBuildPluginManager.java:134)        at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:207)pom.xml文件也是snapshot的（release权限控制，不能再本地deloy到中央仓库）
	<groupId>com.xxx</groupId>	<artifactId>nballowance-client</artifactId>	<packaging>jar</packaging>	<version>1.0.4-snapshot</version>
问题出在这里，version版本号snapshot是小写的，改成大写后OK。
2 第二个问题
Caused by: org.apache.maven.plugin.CompilationFailureException: Compilation failureUnable to locate the Javac Compiler in:  d:/jdk1.8.0_101/../lib/tools.jarPlease ensure you are using JDK 1.4 or above andnot a JRE (the com.sun.tools.javac.Main class is required).In most cases you can change the location of your Javainstallation by setting the JAVA_HOME environment variable.检查 JAVA_HOME 符合预期
$ echo $JAVA_HOMED:/jdk1.8.0_101解决办法
新建一个文件夹命名为lib，拷贝 tools.jar文件到新建的lib文件夹，把lib文件夹拷贝到和jdk1.8.0_101文件夹同级的目录（D盘下）
然后执行 mvn clean deploy 解决。
