Question

我使用Maven 3.3.9和Maven Dependency Plugin版本2.4以GraphML格式生成模块依赖关系树。应将此文件导入yed等工具以生成依赖关系图。

我使用以下命令进行测试：

mvn dependency:tree -DoutputType=graphml -DoutputFile=dependency.graphml

我遇到的问题是，文件中的每个节点都有太多信息供我满足。这使我的图表变得难以理解。

我得到的是输出（这是一个例子）：

org.apache.maven.plugins:maven-dependency-plugin:maven-plugin:2.0-alpha-5-SNAPSHOT

我想要的是什么（这是一个例子）：

maven-dependency-plugin

如何修改输出格式以满足我的需求？

Answer 1

获得当前＆amp;期望的输出并了解目的（如果可能），因为maven具有许多功能，我们可以阻止您“重新发明轮子”并节省您的时间。

我已经阅读了docs，似乎他们没有公开接口来排除/包含部分依赖项，到目前为止最好的解决方案是使用grep

$ mvn -v
Apache Maven 3.3.9

输出类型点对于grepping

更友好

$ mvn dependency:tree -DoutputType=dot

首先grep所有>

行

$ mvn dependency:tree -DoutputType=dot | grep \>
[INFO]  "com.a:test:jar:1.0" -> "org.apache.httpcomponents:httpclient:jar:4.5.5:compile" ; 
[INFO]  "com.a:test:jar:1.0" -> "com.google.code.gson:gson:jar:2.8.2:compile" ;

[INFO]  "org.apache.httpcomponents:httpclient:jar:4.5.5:compile" -> "commons-logging:commons-logging:jar:1.2:compile" ; 
[INFO]  "org.apache.httpcomponents:httpclient:jar:4.5.5:compile" -> "commons-codec:commons-codec:jar:1.10:compile" ;

在>

之后获取字符串

$ mvn dependency:tree -DoutputType=dot | grep \> | cut -d\> -f2
 "org.apache.httpcomponents:httpclient:jar:4.5.5:compile" ; 
 "com.google.code.gson:gson:jar:2.8.2:compile" ; 
 "info.picocli:picocli:jar:2.3.0:compile" ; 
 "log4j:log4j:jar:1.2.17:compile" ; 
 "org.xerial:sqlite-jdbc:jar:3.21.0:compile" ; 
 "org.apache.httpcomponents:httpcore:jar:4.4.9:compile" ; 
 "commons-logging:commons-logging:jar:1.2:compile" ; 
 "commons-codec:commons-codec:jar:1.10:compile" ;

用冒号分割字符串，得到第二个匹配

$ mvn dependency:tree -DoutputType=dot | grep \> | cut -d\> -f2 | cut -d: -f2
httpclient
gson
picocli
log4j
sqlite-jdbc
httpcore
commons-logging
commons-codec

在“：tree”和“BUILD SUCCESS”之间拉线

$ mvn dependency:tree | awk '/:tree/,/BUILD SUCCESS/' [INFO] --- maven-dependency-plugin:2.8:tree (default-cli) @ test --- [INFO] com.a:test:jar:1.0 [INFO] +- org.apache.httpcomponents:httpclient:jar:4.5.5:compile [INFO] | +- org.apache.httpcomponents:httpcore:jar:4.4.9:compile [INFO] | +- commons-logging:commons-logging:jar:1.2:compile [INFO] | \- commons-codec:commons-codec:jar:1.10:compile [INFO] +- com.google.code.gson:gson:jar:2.8.2:compile [INFO] +- info.picocli:picocli:jar:2.3.0:compile [INFO] +- log4j:log4j:jar:1.2.17:compile [INFO] \- org.xerial:sqlite-jdbc:jar:3.21.0:compile [INFO] ------------------------------------------------------------------------ [INFO] BUILD SUCCESS

从顶部删除两行（使用awk）和底部（使用head）

$ mvn dependency:tree | awk '/:tree/,/BUILD SUCCESS/' | awk 'NR > 2 { print }' | head -n -2 [INFO] +- org.apache.httpcomponents:httpclient:jar:4.5.5:compile [INFO] | +- org.apache.httpcomponents:httpcore:jar:4.4.9:compile [INFO] | +- commons-logging:commons-logging:jar:1.2:compile [INFO] | \- commons-codec:commons-codec:jar:1.10:compile [INFO] +- com.google.code.gson:gson:jar:2.8.2:compile [INFO] +- info.picocli:picocli:jar:2.3.0:compile [INFO] +- log4j:log4j:jar:1.2.17:compile [INFO] \- org.xerial:sqlite-jdbc:jar:3.21.0:compile

拉相关线

$ mvn dependency:tree | awk '/:tree/,/BUILD SUCCESS/' | awk 'NR > 2 { print }' | head -n -2 | grep -o -P '.*(?<=:).*(?=:jar)' [INFO] +- org.apache.httpcomponents:httpclient [INFO] | +- org.apache.httpcomponents:httpcore [INFO] | +- commons-logging:commons-logging [INFO] | \- commons-codec:commons-codec [INFO] +- com.google.code.gson:gson [INFO] +- info.picocli:picocli [INFO] +- log4j:log4j [INFO] \- org.xerial:sqlite-jdbc

使用-
删除:（短划线和空格）与sed -e 's/$- $.*$:$/\1\2/'（冒号）之间的字符串，从而删除groupId
$ mvn dependency:tree | awk '/:tree/,/BUILD SUCCESS/' | awk 'NR > 2 { print }' | head -n -2 | grep -o -P '.*(?<=:).*(?=:jar)' | sed -e 's/$- $.*$:$/\1\2/' [INFO] +- :httpclient [INFO] | +- :httpcore [INFO] | +- :commons-logging [INFO] | \- :commons-codec [INFO] +- :gson [INFO] +- :picocli [INFO] +- :log4j [INFO] \- :sqlite-jdbc

使用tr
删除不需要的冒号
$ mvn dependency:tree | awk '/:tree/,/BUILD SUCCESS/' | awk 'NR > 2 { print }' | head -n -2 | grep -o -P '.*(?<=:).*(?=:jar)' | sed -e 's/$- $.*$:$/\1\2/' | tr -d : [INFO] +- httpclient [INFO] | +- httpcore [INFO] | +- commons-logging [INFO] | \- commons-codec [INFO] +- gson [INFO] +- picocli [INFO] +- log4j [INFO] \- sqlite-jdbc

更新2：

虽然你完全改变了你的问题，但这是一个奇特的单行答案：

mvn dependency:tree -DoutputType=graphml -DoutputFile=dependency.graphml && python -c "exec(\"from bs4 import BeautifulSoup;bs = BeautifulSoup(open('dependency.graphml'), 'xml')\\nfor e in bs.find_all('NodeLabel'): e.string = e.string.split(':')[1]\\nprint(bs.prettify())\")" > dependency_fixed.graphml

生成依赖关系树w /

mvn dependency:tree -DoutputType=graphml -DoutputFile=dependency.graphml

完成后（这就是为什么&&）它将执行python脚本

from bs4 import BeautifulSoup bs = BeautifulSoup(open('dependency.graphml'), 'xml') for e in bs.find_all('NodeLabel'): e.string = e.string.split(':')[1] print(bs.prettify()) # print(bs) will print the minified version

迭代NodeLabel元素，用冒号结果替换分割的第二个元素，并用> dependency_fixed.graphml
将其保存到文件中
