On Java1.5, Ant tries to get 31 this from the OS, unless you use the -noproxy option. 32 33 Proxies can be configured manually setting the JVM proxy values in the 34 ANT_OPTS environment variable. 35 36 For example, to set the proxy up in the tcsh shell, the command would be 37 something like: 38 39 For csh/tcsh: 40 setenv ANT_OPTS "-Dhttp.proxyHost=proxy -Dhttp.proxyPort=8080" 41 For bash: 42 export ANT_OPTS="-Dhttp.proxyHost=proxy -Dhttp.proxyPort=8080" 43 For Windows, set the environment variable in the appropriate dialog box 44 and open a new console. or, by hand 45 set ANT_OPTS = -Dhttp.proxyHost=proxy -Dhttp.proxyPort=8080 46</description> 47 48 <property file="get-m2.properties" /> 49 50 <property name="m2.antlib.resource" 51 value="org/apache/maven/artifact/ant/antlib.xml" /> 52 53 <property name="m2.antlib.uri" 54 value="antlib:org.apache.maven.artifact.ant" /> 55 56 <macrodef name="require"> 57 <attribute name="property" /> 58 <sequential> 59 <fail unless="@{property}">$${@{property}} not specified</fail> 60 </sequential> 61 </macrodef> 62 63 <target name="probe-m2"> 64 <require property="m2.dest.dir" /> 65 <require property="m2.jar.name" /> 66 67 <!-- Look for M2 ant tasks in our classpath--> 68 <property name="m2.artifact" location="${m2.dest.dir}/${m2.jar.name}" /> 69 <available property="m2.antlib.found" resource="${m2.antlib.resource}" /> 70 <condition property="m2.antlib.typefound"> 71 <typefound name="${m2.antlib.uri}:artifact" /> 72 </condition> 73 <available property="m2.artifact.found" file="${m2.artifact}" type="file" /> 74 </target> 75 76 <target name="download-m2" depends="probe-m2" unless="m2.artifact.found"> 77 <require property="m2.antlib.url" /> 78 <echo>Downloading to ${m2.dest.dir}</echo> 79 80 <mkdir dir="${m2.dest.dir}" /> 81 <!-- fetch M2 ant tasks into our repository, if it is not there--> 82 <get src="${m2.antlib.url}" 83 dest="${m2.artifact}" 84 verbose="true" 85 usetimestamp="false" /> 86 </target> 87 88 <target name="dont-validate-m2-checksum" depends="probe-m2" 89 if="m2.artifact.found"> 90 <property name="checksum.equal" value="true" /> 91 </target> 92 93 <target name="validate-m2-checksum" 94 depends="download-m2,dont-validate-m2-checksum" 95 if="m2.sha1.checksum" unless="m2.artifact.found"> 96 <checksum file="${m2.artifact}" 97 algorithm="SHA" 98 property="${m2.sha1.checksum}" 99 verifyProperty="checksum.equal" /> 100 </target> 101 102 <target name="checksum-mismatch" depends="validate-m2-checksum" 103 if="m2.sha1.checksum" unless="checksum.equal"> 104 <delete file="${m2.artifact}" /> 105 <fail> 106 Failed to verify the downloaded file ${m2.antlib.url}" against the checksum 107 coded into libraries.properties. 108 The local copy has been deleted, for security reasons 109 </fail> 110 </target> 111 112 <target name="checksum-match" depends="checksum-mismatch" 113 unless="m2.antlib.found"> 114 <taskdef classpath="${m2.artifact}" resource="${m2.antlib.resource}" 115 uri="${m2.antlib.uri}" /> 116 </target> 117 118 <target name="get-m2" depends="checksum-match" 119 description="Download the Maven2 Ant tasks" /> 120 121</project> 122
