如何使用相同的lib进行编译并在Eclipse上运行？
我有一个作为java项目导入的maven项目。当我运行它时，我得到了
Handling error: NestedServletException, Handler dispatch failed; nested exception is java.lang.NoSuchMethodError: org.apache.commons.lang.time.DateUtils.addDays(Ljava/util/Date;I)Ljava/util/Date;
使用this answer我得到了这一行：
[Loaded org.apache.commons.lang.time.DateUtils from file:/C:/Users/user/.m2/repository/commons-lang/commons-lang/2.0/commons-lang-2.0.jar]
但在pom.xml它是：
<dependency>
<groupId>commons-lang</groupId>
<artifactId>commons-lang</artifactId>
<version>2.6</version>
</dependency>
考虑到我在Java Build Path：
和
我该如何解决这个问题？哪里可以保证比较我的运行与编译库？
修改
这是mvn dependency:tree -Dverbose -Dincludes=commons-lang：
[INFO] com.companyName.gestao.projectName:projectName-webapp:war:1.0.0-SNAPSHOT
[INFO] \- com.companyName.gestao.projectName:projectName-business:jar:1.0.0-SNAPSHOT:compile
[INFO] +- com.companyName.commons.utils:companyName-commons-utils:jar:1.14.5:compile
[INFO] | \- softdes:softdes-all:jar:1.6.23:compile
[INFO] | \- commons-lang:commons-lang:jar:2.6:compile (version managed from 2.0)
[INFO] \- net.sf.jasperreports:jasperreports:jar:companyName-6.4.0.4:compile
[INFO] \- org.codehaus.castor:castor-xml:jar:1.3.3:compile
[INFO] +- org.codehaus.castor:castor-core:jar:1.3.3:compile
[INFO] | \- (commons-lang:commons-lang:jar:2.6:compile - version managed from 2.0; omitted for duplicate)
[INFO] \- (commons-lang:commons-lang:jar:2.6:compile - version managed from 2.0; omitted for duplicate)
在business子项目中运行相同的命令（与webapp项目相同的目录级别）：
[INFO] com.companyName.gestao.projectName:projectName-business:jar:1.0.0-SNAPSHOT
[INFO] +- com.companyName.commons.utils:companyName-commons-utils:jar:1.14.5:compile
[INFO] | \- softdes:softdes-all:jar:1.6.23:compile
[INFO] | \- commons-lang:commons-lang:jar:2.0:compile
所以webapp取决于business，companyName-commons-utils依赖softdes-all，而commons-lang取决于webapp版本2.但commons-lang必须pom.xml使用<exclusion>版本2.6。
我可以通过更改commons-lang的依赖顺序来完成此操作吗？
第二次编辑
在business依赖关系中将BUILD SUCCESS添加到 PS C:\workspace\projectName-dev\webapp> mvn dependency:tree -Dverbose -Dincludes=commons-lang

仍然从2.0版本Jar加载。可以做些什么？
1 个答案:
答案 0 :(得分：0)
正如@LuisMuñoz在评论中所述，我使用较旧的依赖项向所有可能的lib添加了排除项。即使这个Eclipse坚持使用它的旧版本。我去了项目属性＆gt; Java构建路径＆gt;订单和导出和顶部优先于我的新版依赖版本2.6。在此之后它起作用了。听起来像pom定义根本不重要，如果Eclipse配置有最后的话。
