Maven项目打包安装报错？

公司的项目，都是配置好的，我用的IDE是MyEclipse 10.5，配置的是Maven 3.3.9，以前单独打包安装模块没问题，现在一install就报错：

[WARNING] 
[WARNING] Some problems were encountered while building the effective model for ...
[WARNING] 'build.plugins.plugin.version' for org.apache.maven.plugins:maven-resources-plugin is missing. @ ...:[unknown-version], ..., line 47, column 12
[WARNING] 'build.plugins.plugin.version' for org.apache.maven.plugins:maven-compiler-plugin is missing. @ ...:[unknown-version], ..., line 37, column 12
[WARNING] 
[WARNING] It is highly recommended to fix these problems because they threaten the stability of your build.

打开pom发现插件已经安装：

<build>
        <finalName>...</finalName>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>
                    <version>3.1</version>
                    <source>1.7</source>
                    <target>1.7</target>
                    <encoding>UTF-8</encoding>
                </configuration>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-resources-plugin</artifactId>
                <configuration>
                    <version>2.6</version>
                    <encoding>UTF-8</encoding>
                </configuration>
            </plugin>
        </plugins>
    </build>

为什么？该怎么做？

maven通过 groupId + artifactId + version来指定一个依赖的环境。
而你如今并没有version的值。 configuration 里的那些都是给 这个插件传入的参数而已。

分别都要在外面加一个version，如下：

<build>
        <finalName>...</finalName>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.1</version>
                <configuration>
                    <version>3.1</version>
                    <source>1.7</source>
                    <target>1.7</target>
                    <encoding>UTF-8</encoding>
                </configuration>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-resources-plugin</artifactId>
                <version>2.6</version>
                <configuration>
                    <version>2.6</version>
                    <encoding>UTF-8</encoding>
                </configuration>
            </plugin>
        </plugins>
    </build>

另外，这只是个warning，你就是不管它，还是能正常玩的转的

<build>
    <finalName>...</finalName>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <configuration>
                **<version>3.1</version>**
                <source>1.7</source>
                <target>1.7</target>
                <encoding>UTF-8</encoding>
            </configuration>
        </plugin>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-resources-plugin</artifactId>
            <configuration>
                **<version>2.6</version>**
                <encoding>UTF-8</encoding>
            </configuration>
        </plugin>
    </plugins>
</build>

version 写错位置了吧。^_^
