JDK:1.7
Maven编译器插件:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.3.2</version>
</plugin>
当我运行install target
以上出现错误时,我如何解决它?

可能正在使用某个版本的maven war plugin,该版本不适用于Java 7?根据this issue(它描述了一个类似的问题),
2.1.1
版本的maven war插件应该可以工作。在pom.xml中包含以下内容
vhipe2zx2#
我在做
mvn install
时遇到了这个问题。我通过先执行mvn clean
,然后执行mvn install
来解决它。使用Maven 2.1.1、JDK 1.7.0.45。
1l5u6lss3#
已确认:安装了Maven2.x的JDK7将产生此错误。
我使用的是Maven2.2.1和JDK7,并收到了这个错误。我将JDK更改为1.6版,它运行良好。

Instead of changing JDK versions and Maven versions, try this:
ltqd579y5#
确认后,我在Maven 3.0.2和JDK 1.7.0_02上遇到了同样的问题。在运行JDK 1.6.0_30之后,它编译得很好。

我不认为版本是问题所在。我解决了删除目标文件夹(因为它包含webapp-cache.xml)并再次执行Maven安装的问题。

ApacheMaven WAR插件3.0.0解决了所有问题:
无论您使用的是JDK 1.6、1.7还是1.8
9vw9lbht8#
这显然与插件、库和语言版本不兼容有关。
两年后,也就是两个Java版本之后,我在做一本关于Spring和Hibernate的旧书中的样例项目时遇到了同样的错误。
我能够通过注解掉apache.maven.plugins的所有版本标记并将Java版本设置为1.8来解决该错误。这让我知道了这些库的最新和最好的版本,代价是Maven发出了一些关于缺少版本标记的警告。如果您关心这些警告,您可以将版本标记设置为最新版本,而来自Maven的警告应该会消失。
我执行了
mvn clean package
,然后只执行了mvn package
。6psbrbz99#
如果您使用的是JDK 1.6,请将此插件条目添加到pom.xml中

我的EclipseKepler遇到了这个问题。我一搬到4.4时(露娜),就都没了。一定是嵌入了eclipse+maven的问题。
我同时尝试了JDK 1.7和1.8。没什么不同。
6xfqseft11#
对我来说,更改插件版本并不能解决问题,更改JDK版本也不在我的控制范围之内。
但是,在
mvn tomcat6:deploy
之前运行mvn clean
解决了这个问题。8nuwlpux12#
确保构建路径中的JDK版本与SOURCE标记中指定的版本相同。
我在源标记中将构建路径指向JDK 1.7和“1.6”,当我在源标记中将版本更正为1.7时,问题就解决了。
执行MNV CLEAN和MVN包。
yqlxgs2m13#
尝试删除所有缓存。当我删除目标文件夹时,它工作正常。
(目标文件夹是Maven放置所有编译代码的位置)

我得到了相同的错误后,我升级我的Java版本从8到8.x,我修复了它转到pom然后1。右击>maven>添加插件2。输入org.apache.maven,然后查找WAR插件添加它并保存,然后只需清理和安装。应该能行得通。
