Question

我同时设置了JAVA_HOME和ANT_HOME：

damechen@ubuntu:~/apache-tomcat-7.0.42-src$ echo $ANT_HOME 
/home/damechen/tmp/damechen/apache-ant-1.9.1
damechen@ubuntu:~/apache-tomcat-7.0.42-src$ echo $JAVA_HOME 
/usr/lib/jvm/jdk1.7.0.25
damechen@ubuntu:~/apache-tomcat-7.0.42-src$ java -version
java version "1.7.0_25"
Java(TM) SE Runtime Environment (build 1.7.0_25-b15)
Java HotSpot(TM) 64-Bit Server VM (build 23.25-b01, mixed mode)

我试图使用ant来构建tomcat，但由于与build.xml相关的某些原因，它失败了。

任何人都可以帮我一臂之力？非常感谢！

正如例外所说。在尝试使用tomcat-native-1.1.27中的名称/usr/share/java/创建目录时，构建失败。

请给予适当的权利。

您需要阅读Apache tomcat的构建说明：

http://svn.apache.org/repos/asf/tomcat/tc7.0.x/tags/TOMCAT_7_0_42/BUILDING.txt

（3.2）建筑
通过创建$ {tomcat.source} /build.properties来控制构建   文件。

建议始终创建该文件，因为不幸   base.path属性的默认值。您可以从以下开始   文件的内容：
# ----- Default Base Path for Dependent Packages -----
# Replace this path with the directory path where dependencies binaries
# should be downloaded
base.path=/home/me/some-place-to-download-to
通过将base.path属性添加到。来配置它   $ {tomcat.source} /build.properties文件。

base.path属性指定Tomcat依赖项的位置   下载了构建所需的内容。建议放置它   源树之外的目录，这样你就不会浪费你的   时间重新下载库。


警告：base.path属性的默认值是构建脚本   下载构建Tomcat所需的库到/ usr / share / java   目录。在典型的Linux或MacOX系统上，普通用户不会   有权写入此目录。即使你有权访问   那个目录，你可能不适合在那里写。

请注意最后的警告....这是您的问题的根本原因。

build file在失败时调用“download-2”目标：

  <target name="extras-commons-logging-prepare"
          depends="extras-prepare"
          description="Prepare to build web services extras package">

    <antcall target="downloadfile-2">
      <param name="sourcefile.1" value="${commons-logging-src.loc.1}"/>
      <param name="sourcefile.2" value="${commons-logging-src.loc.2}"/>
      <param name="destfile" value="${commons-logging-src.tar.gz}"/>
      <param name="destdir" value="${commons-logging.home}"/>
    </antcall>

    ..
    ..

在build.properties文件中，您已将 commons-logging.home 属性的值设置为您无权创建目录的目录路径，即：

/usr/share/java/...

进一步挖掘我看到default properties文件设置此路径如下：

# ----- Default Base Path for Dependent Packages -----
# Please note this path must be absolute, not relative,
# as it is referenced with different working directory
# contexts by the various build scripts.
base.path=/usr/share/java
#base.path=C:/path/to/the/repository
#base.path=/usr/local

..
..

commons-logging.version=1.1.1
commons-logging.home=${base.path}/commons-logging-${commons-logging.version}
