+# 解决jlink error指南
+
+## 现象
+
+jlink时，如果出现如下错误，参考本文档
+
+```
+"automatic module cannot be used with jlink"
+```
+
+## 解决方法：
+
+1. 为jar生成module-info.class
+
+```shell
+jdeps --ignore-missing-deps --module-path <jar_dir_path> --add-modules <module_name --generate-module-info <out_dir_path> <jar_path>
+javac --patch-module <module_name>=<jar_path> <module-info.java>
+jar uf <jar_path> -C <module_name> <module-info.class>
+```
+
+以本次icu4j为例，先将依赖的jar包copy到libs目录，然后执行：
+
+```shell
+jdeps --ignore-missing-deps --module-path libs --add-modules com.ibm.icu --generate-module-info libs/tmpOut libs/icu4j-73.2.jar
+javac --patch-module com.ibm.icu=libs/icu4j-73.2.jar libs/tmpOut/com.ibm.icu/module-info.java
+jar uf libs/icu4j-73.2.jar -C libs/tmpOut/com.ibm.icu module-info.class
+```
+
+2. pom中添加依赖
+
+```xml
+
+<dependency>
+    <groupId>com.ibm.icu</groupId>
+    <artifactId>icu4j</artifactId>
+    <version>73.2</version>
+    <scope>system</scope>
+    <systemPath>${project.basedir}/libs/icu4j-73.2.jar</systemPath>
+</dependency>
+```
