can not find symbol error in Netbeans 11.2

[Nelligan, Steven M]

I don’t know if this is a Maven, Netbeans, or Java problem….
My .m2 folder was deleted, so I need to rebuild everything and import the 
necessary packages into the .m2 folder.

I have several applications using org.springframework.utl…

I get an error:
Failed to execute goal 
org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on 
project approvalsetupent: Compilation failure
edu/uiuc/fs/approvalsetup/business/ApprovalSetupBean.java:[941,40] cannot find 
symbol
  symbol:   method trimArrayElements(java.lang.String[])
  location: class org.springframework.util.StringUtils

-> [Help 1]

To see the full stack trace of the errors, re-run Maven with the -e switch.
Re-run Maven using the -X switch to enable full debug logging.

Using Netbeans 11.2, Maven 3.6.2, java version 1.7.0_242 (yes, old version of

Looking at the .m2 folder, the classes are being pulled in.

I used winzip to open the “spring-core-3.0.1-RELEASE.jar”
                Found class “StringUtils”
                De-compiled and found the method trimArrayElements(String)
But I getting the red line unter trimArrayElements
        if (FSHelper.isValid(approvedStr)) {
            String[] approvedArray = 
StringUtils.commaDelimitedListToStringArray(approvedStr);
            approvedArray = StringUtils.trimArrayElements(approvedArray);
                                                                 ~~~~~~~~~~~~~~
//            approvedArray = trimArrayElements(approvedArray);
            for (String approvedRule : approvedArray) {
                String[] split = approvedRule.split("::");
                approvalGroup = split[0];

Also, getting other errors in another project

    method 
org.springframework.jdbc.core.JdbcTemplate.queryForInt(java.lang.String,java.lang.Object[])
 is not applicable
      (actual argument java.lang.String cannot be converted to 
java.lang.Object[] by method invocation conversion)
    method 
org.springframework.jdbc.core.JdbcTemplate.queryForInt(java.lang.String,java.lang.Object[],int[])
 is not applicable
      (actual and formal argument lists differ in length)
    method 
org.springframework.jdbc.core.JdbcTemplate.queryForInt(java.lang.String) is not 
applicable
      (actual and formal argument lists differ in length)
[INFO] 2 errors

All of these are using org.springframework…..

Does anyone have any idea on where to go from here???


Thanks for any help in advance,
