专家找不到课程 [英] maven doesn't find class

问题描述

我继承了一个庞大的maven java项目，无法对其进行编译.

mvn compile

它告诉我即使在本地存储库中也找不到该类.

Failed to execute goal org.codehaus.enunciate:maven-enunciate-plugin:1.25:assemble (default) on project VCWH_Core_QueryService: Execution default of goal org.codehaus.enunciate:maven-enunciate-plugin:1.25:assemble failed: A required class was missing while executing org.codehaus.enunciate:maven-enunciate-plugin:1.25:assemble: com/sun/mirror/apt/AnnotationProcessorFactory

这是pom.xml代码段，告诉它在哪里看:

 <dependency>
  <groupId>com.sun</groupId>
  <artifactId>tools</artifactId>
  <version>1.7</version>
 </dependency>

可以肯定的是，tools-1.7.jar和tools-1.7.pom位于本地存储库中，

\.m2\repository\com\sun\tools\1.7

如果我看着里面的瓶子 jar tf tools-1.7.jar 我可以看到 类别

com/sun/mirror/apt/AnnotationProcessorFactory.class

我还删除了本地存储库中的sun文件夹，并在NetBeans中进行了清理并构建"，并看着sun文件夹回到了本地存储库中，因此我知道与远程存储库的连接很好. >

为什么找不到它?

解决方案

需要将其添加到maven-uncunciate-plugin:

                        <dependencies>
                            <dependency>
                                <groupId>com.sun</groupId>
                                <artifactId>tools</artifactId>
                                <version>1.7</version>
                                <scope>system</scope>
                                <systemPath>C:\Program Files\Java\jdk1.7.0_79\lib\tools.jar</systemPath>
                                <optional>true</optional>
                            </dependency>
                        </dependencies>

现在看起来像这样:

<plugin>
                <groupId>org.codehaus.enunciate</groupId>
                <artifactId>maven-enunciate-plugin</artifactId>
                <version>1.25</version>
                <configuration>
                    <configFile>${basedir}/src/main/webapp/WEB-INF/enunciate.xml</configFile>
                    <compileDebug>false</compileDebug>
                    <addGWTSources>false</addGWTSources>
                    <addActionscriptSources>false</addActionscriptSources>
                </configuration>
                <dependencies>
                    <dependency>
                    <groupId>com.sun</groupId>
                    <artifactId>tools</artifactId>
                    <version>1.7</version>
                    <scope>system</scope>
                    <systemPath>C:\Program Files\Java\jdk1.7.0_79\lib\tools.jar</systemPath>
                    <optional>true</optional>
                    </dependency>
                </dependencies>

                <executions>
                    <execution>
                        <goals>
                            <goal>assemble</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>

然后从8降级到Java7.

I've inherited a huge maven java project and can't get it to compile.

mvn compile

Its telling me it can't find a class even though its right there in the local repo.

Failed to execute goal org.codehaus.enunciate:maven-enunciate-plugin:1.25:assemble (default) on project VCWH_Core_QueryService: Execution default of goal org.codehaus.enunciate:maven-enunciate-plugin:1.25:assemble failed: A required class was missing while executing org.codehaus.enunciate:maven-enunciate-plugin:1.25:assemble: com/sun/mirror/apt/AnnotationProcessorFactory

Here is the pom.xml snippet that tells it where to look:

 <dependency>
  <groupId>com.sun</groupId>
  <artifactId>tools</artifactId>
  <version>1.7</version>
 </dependency>

And sure enough, tools-1.7.jar and tools-1.7.pom are located in the local repo at

\.m2\repository\com\sun\tools\1.7

And if I look inside the jar with jar tf tools-1.7.jar I can see class

com/sun/mirror/apt/AnnotationProcessorFactory.class

I also blew away the sun folder in my local repo and did a "Clean and Build" in NetBeans and watched the sun folder come back into my local repo, so I know the connectivity to the remote repo is good.

Why can't it find it?

解决方案

Need to add this to the maven-enunciate-plugin:

                        <dependencies>
                            <dependency>
                                <groupId>com.sun</groupId>
                                <artifactId>tools</artifactId>
                                <version>1.7</version>
                                <scope>system</scope>
                                <systemPath>C:\Program Files\Java\jdk1.7.0_79\lib\tools.jar</systemPath>
                                <optional>true</optional>
                            </dependency>
                        </dependencies>

Now it looks like this:

<plugin>
                <groupId>org.codehaus.enunciate</groupId>
                <artifactId>maven-enunciate-plugin</artifactId>
                <version>1.25</version>
                <configuration>
                    <configFile>${basedir}/src/main/webapp/WEB-INF/enunciate.xml</configFile>
                    <compileDebug>false</compileDebug>
                    <addGWTSources>false</addGWTSources>
                    <addActionscriptSources>false</addActionscriptSources>
                </configuration>
                <dependencies>
                    <dependency>
                    <groupId>com.sun</groupId>
                    <artifactId>tools</artifactId>
                    <version>1.7</version>
                    <scope>system</scope>
                    <systemPath>C:\Program Files\Java\jdk1.7.0_79\lib\tools.jar</systemPath>
                    <optional>true</optional>
                    </dependency>
                </dependencies>

                <executions>
                    <execution>
                        <goals>
                            <goal>assemble</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>

And then Downgraded to java 7 from 8.
