本文记录了在本地重新构建log4j 1.2.16版本过程中遇到的错误及解决方案，包括调整Maven版本和环境变量设置。

想要查看log4j的源码。因此下载了最新的apache-log4j-1.2.16来看看。

光看还不过瘾，要本机重新打包玩玩。

把构建过程中遇到的错误记录如下：

0.maven版本：
mvn -v
Apache Maven 3.0.4 (r1232337; 2012-01-17 16:44:56+0800)
Maven home: E:\worksofts\apache-maven-3.0.4
Java version: 1.6.0_05, vendor: Sun Microsystems Inc.
Java home: E:\worksofts\bea\jdk160_05\jre
Default locale: zh_CN, platform encoding: GBK
OS name: "windows vista", version: "6.1", arch: "x86", family: "windows"

最开始构建有错误，但是提示不清楚，因此加参数：mvn install -e -X

1.发现错误如下：
[ERROR]
[ERROR] The project log4j:log4j:1.2.16 (D:\eclipse\myprojects\apache-log4j-1.2
.16\pom.xml) has 1 error
[ERROR] 'build.plugins.plugin[org.apache.maven.plugins:maven-antrun-plugin].
dependencies.dependency.scope' for junit:junit:jar must be one of [compile, runt
ime, system] but is 'test'. @ line 303, column 20
[ERROR]
[ERROR]
[ERROR] For more information about the errors and possible solutions, please rea
d the following articles:
[ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/ProjectBuildin
gException

估计应该不是pom.xml的问题，因此考虑换mvn版本试试。更换为 2.2.1

2.更换版本
mvn -v
Apache Maven 2.2.1 (r801777; 2009-08-07 03:16:01+0800)
Java version: 1.6.0_05
Java home: E:\worksofts\bea\jdk160_05\jre
Default locale: zh_CN, platform encoding: GBK
OS name: "windows vista" version: "6.1" arch: "x86" Family: "windows"

再次构建，出现如下错误：
Caused by: org.apache.maven.reporting.MavenReportException:

.java:89)......

3.发现mvn的环境变量设置可能出现错误。重置环境变量。
        set CLASSPATH=
        再次构建：
