为什么Maven报告“校验和验证失败,没有可用的存储库校验和”?

我正在尝试使用此处描述的3个步骤创建自定义Maven存储库 - http://www.javaworld.com/community/node/3968。所以,我遵循了所有步骤,在这里我有了存储库:

D:\maven2>dir /s/b
D:\maven2\com

现在我正在尝试在这样的pom文件中使用hasp工件:

<dependency>
  <groupId>com.safenet</groupId>
  <artifactId>hasp</artifactId>
  <version>1</version>
  <scope>provided</scope>
</dependency>

存储库的引用如下:

<repository>
  <releases>
    <enabled>true</enabled>
    <updatePolicy>always</updatePolicy>
    <checksumPolicy>fail</checksumPolicy>
  </releases>
  <id>dev-builder</id>
  <name>Shunra private repository</name>
  <url>http://dev-builder/maven2</url>
  <layout>default</layout>
</repository>

不幸的是,它没有按预期工作:

我不知道它有什么问题。 md5和sha1文件是使用md5sum和sha1sum实用程序的cygwin端口创建的。不过,Maven报告的校验和不好。

2 个答案:

答案 0 :(得分:11)

我来到这里寻找相同的答案。花了好几个小时试图搞清楚后,我终于发现这种情况发生的原因有两个:

  1. md5sum和shasum创建的校验和并不完全是maven正在寻找的内容
  2. 您需要所有文件的校验和。
  3. 所以基本上javaworld.com上的教程完全或至少部分错误。

    答案是这样的:

    1. -DcreateChecksum=true命令上使用mvn install:install-file参数。
    2. 重命名生成的maven-metadata-local个文件,以删除local部分。
    3. 我决定经常这样做,我会创建一个bash脚本来自动化这个过程,也许你会发现它也很有用。

      我设计了下面的脚本,在temp目录中运行整个过程,然后压缩结果,然后只需上传到自定义存储库。

      #! /bin/bash
      
      USAGE(){
          println "Usage: `basename $0` -g GroupId -a ArtifactId  -f file [-voh] args\n\n";
      
          println "Options:";
          println "   h   Print usage";
          println "   v   Version (Defaults to 1.0)";
          println "   o   Output zip file name (Defaults to GroupId.ArtifactId.zip)";
      
      
      }
      println(){
      
          echo "$1";
      }
      
      
      VERSION="1.0";
      
      # Parse command line options.
      while getopts hv:o:g:a:f: OPT; do

              \?)
                  # getopts issues an error message
              echo "Error: " >&2;

                  ;;

      done
      
      if [ -z "${OUTPUT_FILE}" ]; then
          OUTPUT_FILE="$GROUP_ID.$ARTIFACT_ID.zip";
      fi
      
      
      
      # Remove the switches we parsed above.
      shift `expr $OPTIND - 1`
      
      if [ -z "${ARTIFACT_ID}" ]; then
          echo "Error: You must specify an artifact id."

      fi
      
      if [ ! -f "${INPUT_FILE}" ];
      then
           echo "Error: Input file '$INPUT_FILE' does not exist."
      fi
      
      # Create a temp directory which we will use as our 'local repository'
      TEMPDIR=$(mktemp -dt "build-maven-dep.XXXXXXX")
      
      TEMPDIR_SUB="$GROUP_ID.$ARTIFACT_ID";
      TEMP_REPO_LOC="$TEMPDIR/$TEMPDIR_SUB";
      mkdir -p $TEMP_REPO_LOC;
      
      mvn install:install-file -DlocalRepositoryPath=$TEMP_REPO_LOC -DgroupId=$GROUP_ID -DartifactId=$ARTIFACT_ID -Dversion=$VERSION -Dfile=$INPUT_FILE -Dpackaging=jar -DgeneratePom=true -DcreateChecksum=true
      
      CUR_DIR=$(pwd);
      
      # Enter the temp repository we created which is now populated.
      cd $TEMP_REPO_LOC;
      
      PACKAGE_STRUC="$GROUP_ID.$ARTIFACT_ID";
      
      # Dive down into directory structure until we get to the *.xml files.
      IFS='. ' read -ra ADDR <<< $PACKAGE_STRUC
      for i in "${ADDR[@]}"; do
         println "Moving into: $i";
         cd $i;
         println "Now  in $(pwd)";
      done
      
      # Rename the files to what maven expects.
      mv maven-metadata-local.xml maven-metadata.xml
      mv maven-metadata-local.xml.md5 maven-metadata.xml.md5 
      mv maven-metadata-local.xml.sha1 maven-metadata.xml.sha1
      
      # Zip up our results.
      cd $TEMP_REPO_LOC;
      cd ..;
      zip -r $OUTPUT_FILE $TEMPDIR_SUB
      mv $OUTPUT_FILE $CUR_DIR
      
      # Return back to our original directory and remove the temp directory
      cd $CUR_DIR;
      rm -Rf $TEMPDIR;
      
      # EOF
      

      假设您要将myjar.jar打包为自定义存储库:

      ./bundle-for-remote.sh -g com.mygroup -a myJar -f myJar.jar
      

      这将在当前目录中创建一个名为com.mygroup.myJar.zip的.zip,其中包含所有组件。

      干杯,

答案 1 :(得分:3)

根据您上面粘贴的内容,我在您的存储库中看不到com.shunra:license:jar:0.0.1。尝试将其安装到您的存储库中。或者maven可以找到它。

虽然错误上写着“没有可用的校验和信息”,但我认为它真正想说的是“我甚至找不到它”

另外..如果你喜欢采取快捷方式之一,你可以通过取消&lt; checksumPolicy&gt;失败&lt; / checksumPolicy&gt;

来跳过校验和验证
