Maven项目打包安装报错？

Question

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.

[WARNING] 

[WARNING] For this reason, future Maven versions might no longer support building such malformed projects.

[WARNING] 

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？

Answer 1

分别都要在外面加一个version，如下：<build>&nbsp; &nbsp; &nbsp; &nbsp; <finalName>...</finalName>&nbsp; &nbsp; &nbsp; &nbsp; <plugins>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <plugin>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <groupId>org.apache.maven.plugins</groupId>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <artifactId>maven-compiler-plugin</artifactId>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <version>3.1</version>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <configuration>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <version>3.1</version>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <source>1.7</source>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <target>1.7</target>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <encoding>UTF-8</encoding>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </configuration>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </plugin>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <plugin>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <groupId>org.apache.maven.plugins</groupId>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <artifactId>maven-resources-plugin</artifactId>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <version>2.6</version>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <configuration>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <version>2.6</version>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <encoding>UTF-8</encoding>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </configuration>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </plugin>&nbsp; &nbsp; &nbsp; &nbsp; </plugins>&nbsp; &nbsp; </build>另外，这只是个warning，你就是不管它，还是能正常玩的转的

Answer 3

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。
