最近使用maven自动构建android的签名apk包（配合hudson），遇到几个问题跟大家分享下：
1、使用maven-android-plugin可以很容易实现自动构建，但基于命令行的方式有别与eclipse的打包方式
2、编译时出现非法字符的错误
1
*.java:[1,0] 非法字符： \65279
说明某些文件采用UTF-8的时候写入了BOM的头信息，eclipse采用jdt会自动处理这些头信息但maven直接调用javac没有那么智能了，首先找找那些文件
1
#查找BOM
2
find -type f -name "*.java"|while read file;do [ "`head -c3 -- "$file"`" == $'\xef\xbb\xbf' ] && echo "found BOM in: $file";done
使用vim自动去除bom
1
去掉utf-8 BOM
2
:set nobomb
3、打包是出现无法签名的情况
<plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-jarsigner-plugin</artifactId> <version>1.2</version> <executions> <execution> <id>signing</id> <goals> <goal>sign</goal> </goals> <phase>package</phase> <inherited>true</inherited> <configuration> <archiveDirectory></archiveDirectory> <includes> <include>target/${artifactId}.apk</include> </includes> <keystore>${keyFilePath}</keystore> <storepass>${storePassword}</storepass> <keypass>${keyPassword}</keypass> <alias>${keyAlias}</alias> </configuration> </execution> </executions> </plugin>alias必须与生成签名文件时的条目一致
4、签名之前必须保证apk生成的时候没有使用debug签名，不然会提示
jarsigner： 无法对 jar 进行签名： java.util.zip.ZipException: invalid entry compressed size (expected 15331 but got 15809 bytes)
必须定义maven的android插件信息
<configuration> <sdk> <path>${env.ANDROID_HOME}</path> <platform>7</platform> </sdk> <sign> <debug>false</debug> </sign> <deleteConflictingFiles>true</deleteConflictingFiles> </configuration> 5、至此使用一条命令 mvn clean package就可以自动编译打包了下面是完整的配置 <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.xxxx.gcl</groupId> <artifactId>xxxx</artifactId> <version>2.1.2</version> <packaging>apk</packaging> <name>xxxxxx</name> <dependencies> <dependency> <groupId>com.google.android</groupId> <artifactId>android</artifactId> <version>2.1.2</version> <scope>provided</scope> </dependency> <dependency> <groupId>com.thoughtworks.xstream</groupId> <artifactId>xstream</artifactId> <version>1.3.1</version> </dependency> <dependency> <groupId>com.dom4j</groupId> <artifactId>dom4j</artifactId> <version>1.6.1</version> </dependency> <dependency> <groupId>commons-httpclient</groupId> <artifactId>commons-httpclient</artifactId> <version>3.1</version> </dependency> <dependency> <groupId>com.autonavi</groupId> <artifactId>mapapi</artifactId> <version>1.0</version> </dependency> </dependencies> <build> <finalName>${artifactId}</finalName> <sourceDirectory>src</sourceDirectory> <plugins> <plugin> <groupId> com.jayway.maven.plugins.android.generation2 </groupId> <artifactId>android-maven-plugin</artifactId> <version>3.1.1</version> <configuration> <sdk> <path>${env.ANDROID_HOME}</path> <platform>7</platform> </sdk> <sign> <debug>false</debug> </sign> <deleteConflictingFiles>true</deleteConflictingFiles> </configuration> <extensions>true</extensions> <inherited>true</inherited> </plugin> <plugin> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.6</source> <target>1.6</target> <encoding>UTF-8</encoding> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-jarsigner-plugin</artifactId> <version>1.2</version> <executions> <execution> <id>signing</id> <goals> <goal>sign</goal> </goals> <phase>package</phase> <inherited>true</inherited> <configuration> <archiveDirectory></archiveDirectory> <includes> <include>target/${artifactId}.apk</include> </includes> <keystore>${keyFilePath}</keystore> <storepass>${storePassword}</storepass> <keypass>${keyPassword}</keypass> <alias>${keyAlias}</alias> </configuration> </execution> </executions> </plugin> </plugins> </build> <profiles> <profile> <id>local</id> <activation> <activeByDefault>true</activeByDefault> </activation> <properties> <keyFilePath>xxxxxxx</keyFilePath> <storePassword>xxxx</storePassword> <keyPassword>xxxx</keyPassword> <keyAlias>xxxxx</keyAlias> </properties> </profile> <profile> <id>dev</id> <properties> <keyFilePath>xxxxx</keyFilePath> <storePassword>xxxxx</storePassword> <keyPassword>xxxx</keyPassword> <keyAlias>xxxxxx</keyAlias> </properties> </profile> </profiles></project>
