我正在尝试升级到最新的Java Mail实用程序.
从
<dependency>
<groupId>javax.mail</groupId>
<artifactId>mail</artifactId>
<version>1.4.7</version>
</dependency>
到(我的意图)
<dependency>
<groupId>javax.mail</groupId>
<artifactId>mail</artifactId>
<version>1.5.1</version>
</dependency>
但我找不到1.5.1的邮件工件,
但我可以看到
<dependency>
<groupId>com.sun.mail</groupId>
<artifactId>javax.mail</artifactId>
<version>1.5.1</version>
</dependency>
我的问题是为什么组ID发生了变化,如果我更改了1.5.1的组ID,我是否需要更改已经存在的所有邮件实现(包名更改和其他任何内容)以及com.sun.mailvs 之间的区别是javax.mail什么？
可能重复:
方法finalize和exception
垃圾收集器finalize()在对象即将从内存中释放时调用方法.在finalize()方法中引发异常时会发生什么？
GC会继续进行并释放内存,否则GC将暂停该对象的进程？
我在Hudson中运行Job时遇到问题.我已经使用ANT_HOME配置了Hudson,其中包含ant和JDK的路径以及相对路径.我创建了一个新工作,在那里我设置了SVN路径和其他东西.我的项目的build.xml位于Project root Folder/build/build.xml中
他们在Linux中添加了build.xml.这是这样的.
<project name="Test Job" default="build">
<target name="clean">
<delete dir="${basedir}/svn/_build"/>
<delete dir="${basedir}/build"/>
</target>
<target name="prepare">
<mkdir dir="${basedir}/svn/_build/logs"/>
<mkdir dir="${basedir}/build/logs"/>
<mkdir dir="${basedir}/build/docs"/>
</target>
<target name="build"
depends="clean,prepare"/>
</project>
注意:我将我的工作名称设置为usercentral.
然后我尝试在Hudson上构建.它给了我以下错误.
FATAL: command execution failed.Maybe you need to configure the job to choose one of your Ant installations?
java.io.IOException: Cannot run program "ant" (in directory "/root/.hudson/jobs/userCentral/workspace/branches/branches/build"): java.io.IOException: error=2, No such file or directory

谢谢您的帮助.
