第一次使用自己上传的maven库时遇到的错误总结

背景：好不容易将自己的jar包上传到maven中心，可以下载了，结果使用的时候，报各种错误。

错误1:

wudideMacBook-Pro:UCarNew xiepengchong$ ./gradlew tasks

Parallel execution with configuration on demand is an incubating feature.

FAILURE: Build failed with an exception.

* Where:

Build file '/Users/xiepengchong/ucar_git/ucarandroid/UCarNew/build.gradle' line: 27

* What went wrong:

A problem occurred evaluating root project 'UCarNew'.

原因：原来是我的版本不对，后来将build tool版本更改了一下。gradle版本改为2.10，

classpath 'com.android.tools.build:gradle:2.1.2'

错误2:

* Where:Build file '/Users/xiepengchong/ucar_git/ucarandroid/UCarNew/build.gradle' line: 32
* What went wrong:A problem occurred evaluating root project 'UCarNew'.> Could not find implementation class 'com.droidtitan.lintcleaner.LintCleanerPlugin' for plugin 'com.droidtitan.lintcleaner' specified in jar:file:/Users/xiepengchong/ucar_git/ucarandroid/UCarNew/external_lib/lint-cleaner-plugin-1.0.1.jar!/META-INF/gradle-plugins/com.droidtitan.lintcleaner.properties.原因：

我上传的jar包中，没有class文件，原来我的工程是使用groovy写的，所以有一些东西和java的不同，所以需要单独配置。

在pom.xml中指定路径

 87   <build> 88     <sourceDirectory>src/main/groovy</sourceDirectory> 89     <resources> 90       <resource> 91         <directory>src/main/resources</directory> 92           <includes> 93             <include>**/*.*</include> 94           </includes> 95       </resource> 96     </resources>

错误：指定之后，还需要使之可以编译进去，需要在pom.xml中配置下面的信息

mvn compile

 98       <plugin> 99         <groupId>org.codehaus.gmaven</groupId>100         <artifactId>gmaven-plugin</artifactId>101         <version>1.2</version>102         <configuration>103           <providerSelection>1.7</providerSelection>104           <sourceEncoding>UTF-8</sourceEncoding>105         </configuration>106         <executions>107           <execution>108             <goals>109               <goal>generateStubs</goal>110               <goal>compile</goal>111             </goals>112           </execution>113         </executions>114       </plugin>

错误：编译的时候，各种路径找不到

原因：我们使用gradle编译，系统下好多jar都是配置好的，如果用maven编译，则需要指定，在pom.xml指定我们本地以来jar文件

 58     <dependency> 59       <groupId>gradle-core</groupId> 60       <artifactId>gradle-core</artifactId> 61       <version>2.10</version> 62       <scope>system</scope> 63       <systemPath>${project.basedir}/libs/gradle-core-2.10.jar</systemPath> 64     </dependency> 65     <dependency> 66       <groupId>gradle-base-services-groovy</groupId> 67       <artifactId>gradle-base-services-groovy</artifactId> 68       <version>2.10</version> 69       <scope>system</scope> 70       <systemPath>${project.basedir}/libs/gradle-base-services-groovy-2.10.jar</systemPath> 71     </dependency> 72     <dependency> 73       <groupId>gradle-base-services</groupId> 74       <artifactId>gradle-base-services</artifactId> 75       <version>2.10</version> 76       <scope>system</scope> 77       <systemPath>${project.basedir}/libs/gradle-base-services-2.10.jar</systemPath> 78     </dependency> 79     <dependency> 80       <groupId>gradle-model-core</groupId> 81       <artifactId>gradle-model-core</artifactId> 82       <version>2.10</version> 83       <scope>system</scope> 84       <systemPath>${project.basedir}/libs/gradle-model-core-2.10.jar</systemPath> 85     </dependency>

错误：一切都结束了，但是发现我们部署的时候，没有上传javadoc和source,所以部署的时候，会有问题。

原因：同样需要在build的时候，配置plugin

115       <plugin>116         <groupId>org.apache.maven.plugins</groupId>117         <artifactId>maven-source-plugin</artifactId>118         <version>2.4</version>119         <configuration>120           <attach>true</attach>121         </configuration>122           <executions>123             <execution>124               <id>attach-sources</id>125               <phase>package</phase>126               <goals>127                 <goal>jar-no-fork</goal>128               </goals>129             </execution>130           </executions>131        </plugin>132        <plugin>133          <groupId>org.apache.maven.plugins</groupId>134          <artifactId>maven-javadoc-plugin</artifactId>135          <version>2.10.2</version>136          <configuration>137            <aggregate>true</aggregate>138          </configuration>139          <executions>140            <execution>141               <id>attach-javadocs</id>142               <goals>143                 <goal>jar</goal>144               </goals>145             </execution>146           </executions>147       </plugin>

这回上传就等待审核吧。
