新手村新手，环境问题

[Dhaizei]

目前在ubuntu下，有gradle环境和openjdk version "16.0.1" 但是第一步编译就把我拦下来了， 编译： gradlew jar 出错：

Command 'gradlew' not found, did you mean:

command 'gradle' from deb gradle (4.4.1-13)

Try: apt install

我就用 ./gradlew jar

然后就 Starting a Gradle Daemon (subsequent builds will be faster)

FAILURE: Build failed with an exception.

• Where: Build file '/root/data/java-callgraph2/build.gradle'

• What went wrong: Could not compile build file '/root/data/java-callgraph2/build.gradle'.

startup failed: General error during semantic analysis: Unsupported class file major version 60

貌似是安装java环境的版本不支持，我换了11 sudo apt install openjdk-11-jdk 这个不行，所以我该怎么办啊？ 求贴主，帮我解答一下

[Adrninistrator]

试一下用jdk8来编译，更高版本的可能需要升级gradle的版本了

[Dhaizei]

试了不行，欸我换了jdk8最低版本。gradle 是7.4.2-0ubuntu1

[Dhaizei]

jdk18我也试了……

[Adrninistrator]

gradle用6.x版本试一下

[Dhaizei]

好，谢谢贴主，我去试试

[Dhaizei]

我装了gradle6.5的版本，还是报之前的错误 从60到62，之前更新java环境的时候也是报的这个错误 java.lang.IllegalArgumentException: Unsupported class file major version 62

[Adrninistrator]

用JDK8+Gradle 6.x应该是没有问题的，需要检查一下实际使用的JDK版本

[Dhaizei]

好的，谢谢啦，我再去试试

[Dhaizei]

最后 解决了 ~谢谢

[Adrninistrator]

不客气的，解决了就好，后面在文档里把需要的环境说明写详细一点

[Dhaizei]

贴主大大，我又遇到问题了，目前我运行到这一步了：

我看了配置文件_javacg_config/config.properties 但是没有找到输入文件目录的变量

然后我仔细看了看readme，相关输入目录的描述是下面的： out build/libs/a.jar build/libs/a.jar build/libs/b.jar out build/libs/a.jar build/libs/b.jar

我不理解，out是什么

[Adrninistrator]

out是idea生成class的目录

[Dhaizei]

那我该怎么解析一个jar文件呢，实在是我没看懂怎么执行

[Adrninistrator]

在jar_dir.properties里指定jar包路径就可以

[Adrninistrator]

用的配置文件和以前不一样了，文档还没来得及仔细改

[Dhaizei]

比如：jar_dir.properties = /root/data/java-callgraph2/jar_output_dir/jar/run_javacg2.jar 这个？

[Dhaizei]

会了，谢谢 直接将下面的路径贴到jar_dir.properties里面就行了 /root/data/java-callgraph2/jar_output_dir/jar/run_javacg2.jar

[Dhaizei]

还有个问题麻烦您了： 这是我的运行文件/root/data/java-callgraph2/build/libs 就是咱们git仓库自带的文件，为什么我解析后的文件是 没有z找到调用关系的文件。如果可以的话，有测试样例吗

[Adrninistrator]

如果指定目录的话，目录里要有需要解析的jar包 如果有的话，看一下method_call.txt文件，如果内容是空的话，检查一下libs-javacg_merged.jar文件里有没有指定的jar包

[Dhaizei]

比如下面的是什么意思呢？我在您的输出文件格式内容看了，也没理解下面的意思 1 copy.javassist.bytecode.SignatureAttribute$TypeVariable:(java.lang.String,int,int) (SPE)copy.javassist.bytecode.SignatureAttribute$ObjectType:() 732 t void 2 2 2 copy.javassist.bytecode.SignatureAttribute$TypeVariable:(java.lang.String,int,int) (VIR)java.lang.String:substring(int,int) 733 v java.lang.String 2 - 3 copy.javassist.bytecode.SignatureAttribute$TypeVariable:(java.lang.String) (SPE)copy.javassist.bytecode.SignatureAttribute$ObjectType:() 741 t void 2 2

[Adrninistrator]

上面的文件代表前面的方法调用了后面的方法，文件每一列的说明我增加一下

[Adrninistrator]

增加了文档 https://github.com/Adrninistrator/java-callgraph2/blob/main/docs
