How to really read text file from classpath in Java
I changed my code then to
inventoryPriceDetails = mapper.readValue(getClass().getResourceAsStream("/getInventoryAndPriceResponse.json"), new TypeReference<List<InventoryPriceDetail>>() {});
Problem
I have a project with multiple maven modules ``` project/pom.xml /external_services/pom.xml /ifs/pom.xml /src/test/java/ /MockIFSClient.java /IFSClientTest.java /src/test/java/resources/sample.json /inventory/pom.xml /business/pom.xml /src/main/java/InventorySummary.java /services/pom.xml /src/main/java/InventorySummaryResource.java /src/main/test/InventorySummaryResourceTest.java ``` MockIFSClient access `sample.json` as ``` try { inventoryPriceDetails = mapper.readValue(new File(getClass().getResource("/getInventoryAndPriceResponse.json").getPath()), new TypeReference<List<InventoryPriceDetail>>() { }); } catch (final IOException e) { throw new RuntimeException("could not read resource :" + e.getMessage()); } ``` so IFSClientTest runs fins since they are in same package. Problem? `InventorySummaryResourceTest` calls `MockIFSClient` which tries to access the same code, but now it fails as ``` could not read resource :file:/Users/harith/IdeaProjects/inventory_api/external_services/ifs/target/ifs-1.0-SNAPSHOT-tests.jar!/sample.json (No such file or directory) ``` services/pom.xml has dependency as ``` <dependency> <groupId>com.org.project.external_services</groupId> <artifactId>ifs</artifactId> <version>${project.version}</version> <type>test-jar</type> <scope>test</scope> </dependency> ``` Question What change do I make to ``` new File(getClass().getResource("/getInventoryAndPriceResponse.json").getPath()) ``` so that it can be accessed from different modules as well
